2012-06-15Btrfs: fix missing inherited flag in renameLiu Bo1-3/+6
When we move a file into a directory with compression flag, we need to inherite BTRFS_INODE_COMPRESS and clear BTRFS_INODE_NOCOMPRESS as well. But if we move a file into a directory without compression flag, we need to clear both of them. It is the way how our setflags deals with compression flag, so keep the same behaviour here.

2012-06-15Make hard_irq_disable() actually hard-disable interruptsPaul Mackerras1-0/+3
At present, hard_irq_disable() does nothing on powerpc because of this code in include/linux/interrupt.h: #ifndef hard_irq_disable #define hard_irq_disable() do { } while(0) #endif So we need to make our hard_irq_disable be a macro. It was previously a macro until commit 7230c56441 ("powerpc: Rework lazy-interrupt handling") changed it to a static inline function.

2012-06-14Btrfs: fix incompat flags settingLi Zefan1-1/+1
It's a bug, but it happens to work, as BTRFS_COMPRESS_LZO == 2, which has only one bit set. Signed-off-by: Li Zefan <[email protected]>
2012-06-14Btrfs: fix defrag regressionLi Zefan1-48/+49
If a file has 3 small extents: | ext1 | ext2 | ext3 | Running "btrfs fi defrag" will only defrag the last two extents, if those extent mappings hasn't been read into memory from disk. This bug was introduced by commit 17ce6ef8d731af5edac8c39e806db4c7e1f6956f ("Btrfs: add a check to decide if we should defrag the range") The cause is, that commit looked into previous and next extents using lookup_extent_mapping() only. While at it, remove the code that checks the previous extent, since it's sufficient to check the next extent. Signed-off-by: Li Zefan <[email protected]>
2012-06-14Btrfs: call filemap_fdatawrite twice for compressionJosef Bacik3-7/+31
I removed this in an earlier commit and I was wrong. Because compression can return from filemap_fdatawrite() without having actually set any of it's pages as writeback() it can make filemap_fdatawait() do essentially nothing, and then we won't find any ordered extents because they may not have been created yet. So not only does this make fsync() completely useless, but it will also screw up if you truncate on a non-page aligned offset since we zero out the end and then wait on ordered extents and then call drop caches. We can drop the cache before the io completes and then we try to unpin the extent we just wrote we won't find it and everything goes sideways. So fix this by putting it back and put a giant comment there to keep me from trying to remove it in the future. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: keep inode pinned when compressing writesJosef Bacik1-2/+6
A user reported lots of problems using compression on the new code and it turns out part of the problem was that igrab() was failing when we added a new ordered extent. This is because when writing out an inode under compression we immediately return without actually doing anything to the pages, and then in another thread at some point down the line actually do the ordered dance. The problem is between the point that we start writeback and we actually add the ordered extent we could be trying to reclaim the inode, which makes igrab() return NULL. So we need to do an igrab() when we create the async extent and then drop it when we are done with it. This makes sure we stay pinned in memory until the ordered extent can get a reference on it and we are good to go. With this patch we no longer panic in btrfs_finish_ordered_io(). Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: implement ->show_devnameJosef Bacik1-0/+33
Because btrfs can remove the device that was mounted we need to have a ->show_devname so that in this case we can print out some other device in the file system to /proc/mount. So if there are multiple devices in a btrfs file system we will just print the device with the lowest devid that we can find. This will make everything consistent and deal with device removal properly. The drawback is if you mount with a device that is higher than the lowest devicd it won't show up as the mounted device in /proc/mounts, but this is a small price to pay. This was inspired by Miao Xie's patch. Thanks, Reviewed-by: Miao Xie <[email protected]> Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: use rcu to protect device->nameJosef Bacik8-64/+162
Al pointed out that we can just toss out the old name on a device and add a new one arbitrarily, so anybody who uses device->name in printk could possibly use free'd memory. Instead of adding locking around all of this he suggested doing it with RCU, so I've introduced a struct rcu_string that does just that and have gone through and protected all accesses to device->name that aren't under the uuid_mutex with rcu_read_lock(). This protects us and I will use it for dealing with removing the device that we used to mount the file system in a later patch.

2012-06-14Btrfs: unlock everything properly in the error case for nocowJosef Bacik1-2/+35
I was getting hung on umount when a transaction was aborted because a range of one of the free space inodes was still locked. This is because the nocow stuff doesn't unlock anything on error. This fixed the problem and I verified that is what was happening. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: fix btrfs_destroy_marked_extentsJosef Bacik1-4/+2
So we're forcing the eb's to have their ref count set to 1 so invalidatepage works but this breaks lots of things, for example root nodes, and is just plain wrong, we don't need to just evict all of this stuff. Also drop the invalidatepage altogether and add a page_cache_release(). With this patch we no longer hang when trying to access the root nodes after an aborted transaction and we no longer leak memory. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: abort the transaction if the commit failsJosef Bacik1-2/+8
If a transaction commit fails we don't abort it so we don't set an error on the file system. This patch fixes that by actually calling the abort stuff and then adding a check for a fs error in the transaction start stuff to make sure it is caught properly. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: wake up transaction waiters when aborting a transactionJosef Bacik2-6/+7
I was getting lots of hung tasks and a NULL pointer dereference because we are not cleaning up the transaction properly when it aborts. First we need to reset the running_transaction to NULL so we don't get a bad dereference for any start_transaction callers after this. Also we cannot rely on waitqueue_active() since it's just a list_empty(), so just call wake_up() directly since that will do the barrier for us and such. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: fix locking in btrfs_destroy_delayed_refsJosef Bacik1-13/+17
The transaction abort stuff was throwing warnings from the list debugging code because we do a list_del_init outside of the delayed_refs spin lock. The delayed refs locking makes baby Jesus cry so it's not hard to get wrong, but we need to take the ref head mutex to make sure it's not being processed currently, and so if it is we need to drop the spin lock and then take and drop the mutex and do the search again. If we can take the mutex then we can safely remove the head from the list and carry on. Now when the transaction aborts I don't get the list debugging warnings. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2012-06-14Btrfs: pass locked_page into extent_clear_unlock_delalloc if theres an errorJosef Bacik1-2/+2
While doing my enospc work I got a transaction abortion that resulted in a panic when we tried to unlock_page() an already unlocked page. This is because we aren't calling extent_clear_unlock_delalloc with the locked page so it was unlocking all the pages in the range. This is wrong since __extent_writepage expects to have the page locked still unless we return *page_started as 1. This should keep us from panicing.

2012-06-14USB: fix gathering of interface associationsDaniel Mack1-1/+2
TEAC's UD-H01 (and probably other devices) have a gap in the interface number allocation of their descriptors: Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 220 bNumInterfaces 3 [...] Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 [...] Interface Association: bLength 8 bDescriptorType 11 bFirstInterface 2 bInterfaceCount 2 bFunctionClass 1 Audio bFunctionSubClass 0 bFunctionProtocol 32 iFunction 4 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 2 bAlternateSetting 0 [...] Once a configuration is selected, usb_set_configuration() walks the known interfaces of a given configuration and calls find_iad() on each of them to set the interface association pointer the interface is included in. The problem here is that the loop variable is taken for the interface number in the comparison logic that gathers the association. Which is fine as long as the descriptors are sane. In the case above, however, the logic gets out of sync and the interface association fields of all interfaces beyond the interface number gap are wrong. Fix this by passing the interface's bInterfaceNumber to find_iad() instead.

A simplified call graph looks like this: pygrub QEMU ----------------------------------------------- do_read_cache_page io_submit | | lock_page ext3_direct_IO | bio_add_page | lock_page Internally the xen-blkback uses m2p_add_override to swizzle (temporarily) a 'struct page' to have a different MFN (so that it can point to another guest). It also can easily find out whether another pfn corresponding to the mfn exists in the m2p, and can set the FOREIGN bit in the p2m, making sure that mfn_to_pfn returns the pfn of the backend. This allows the backend to perform direct_IO on these pages, but as a side effect prevents the frontend from using get_user_pages_fast on them while they are being shared with the backend.

To make sense of the tree mod log, the backref walker not only needs btrfs_search_old_slot, but it also called btrfs_next_leaf, which in turn was calling btrfs_search_slot. This obviously didn't give the correct result. This commit adds btrfs_next_old_leaf, a drop-in replacement for btrfs_next_leaf with a time_seq parameter.

2012-06-14Btrfs: remove obsolete btrfs_next_leaf call from __resolve_indirect_refJan Schmidt1-9/+1
When resolving indirect refs, we used to call btrfs_next_leaf in case we didn't find an exact match. While we should find exact matches most of the time, in case we don't, we must continue searching. Treating those matches differently depending on the level we're searching doesn't make sense. Even worse, we might end up searching for a key larger than the largest, in which case there is no next_leaf and subsequent jobs would fail. This commit drops the bogous lines.

2012-06-14Bluetooth: Fix sending HCI_Disconnect only when connectedVishal Agarwal1-1/+1
HCI_Disconnect should only be sent after connection is established. If connection is not yet established and HCI_Disconnect is called then disconnection complete will be received with a handle which does not exist and hence this event will be ignored. But as mgmt.c will not receive this event, its variable for pending command is not cleared.This will result in future Disconnect commands for that BD Address to be blocked with error busy.

2012-06-14ARM: 7422/1: mmc: mmci: Allocate platform memory during Device Tree bootLee Jones1-0/+6
When booting with Device Tree enabled, platform specific information is gathered by parsing the DT binary. Platform data is subsequently populated with the result. The memory required for this is not automatically allocated during Device Tree boot, so we'll do it here instead.

2012-06-14watchdog: Quiet down the boot messagesDon Zickus1-1/+18
A bunch of bugzillas have complained how noisy the nmi_watchdog is during boot-up especially with its expected failure cases (like virt and bios resource contention). This is my attempt to quiet them down and keep it less confusing for the end user. What I did is print the message for cpu0 and save it for future comparisons. If future cpus have an identical message as cpu0, then don't print the redundant info. However, if a future cpu has a different message, happily print that loudly. Before the change, you would see something like: ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 CPU0: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz stepping 0a Performance Events: PEBS fmt0+, Core2 events, Intel PMU driver. ... version: 2 ... bit width: 40 ... generic registers: 2 ... value mask: 000000ffffffffff ... max period: 000000007fffffff ... fixed-purpose events: 3 ... event mask: 0000000700000003 NMI watchdog enabled, takes one hw-pmu counter.

Brought up 4 CPUs Total of 4 processors activated (22607.24 BogoMIPS). After the change, it is simplified to: ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 CPU0: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz stepping 0a Performance Events: PEBS fmt0+, Core2 events, Intel PMU driver. ... version: 2 ... bit width: 40 ... generic registers: 2 ... value mask: 000000ffffffffff ... max period: 000000007fffffff ... fixed-purpose events: 3 ... event mask: 0000000700000003 NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.

2012-06-14DMA: PL330: Fix racy mutex unlockJavi Merino1-16/+10
pl330_update() stores a pointer to the thrd->req that finished, which contains a pointer to the corresponding pl330_req. This is done with the pl330_lock held. Then, it iterates through the req_done list, calling the callback for each of the requests that are done. The problem is that the driver releases the lock before calling the callback for each of the callbacks. pl330_submit_req() running in another processor can then acquire the lock and insert another request in one of the thrd->req that hasn't been processed yet, replacing the pointer to pl330_req there. When the callback returns in pl330_update() and the next rqdone is popped from the list, it dereferences the pl330_req pointer to the just scheduled pl330_req, instead of the one that has finished, calling pl330 with the wrong r. This patch fixes this by storing the pointer to pl330_req directly in the list.

2012-06-13Fix OMAP EHCI suspend/resume failure (i693)Anand Gadiyar1-1/+167
Its observed with some PHY, the 60Mhz clock gets cut too soon for OMAP EHCI, leaving OMAP-EHCI in a bad state. So on starting port suspend, make sure the 60Mhz clock to EHCI is kept alive using an internal clock, so that EHCi can cleanly transition its hw state machine on a port suspend. Its not proven if this is the issue hit on USB3333, but the symptoms look very similar.
