2010-12-02cs5535-gpio: apply CS5536 errata workaround for GPIOsAndres Salomon1-2/+14
The AMD Geode CS5536 Companion Device Silicon Revision B1 Specification Update mentions the follow as issue #36: "Atomic write transactions to the atomic GPIO High Bank Feature Bit registers should only affect the bits selected [...]" "after Suspend, an atomic write transaction [...] will clear all non-selected bits of the accessed register." In other words, writing to the high bank for a single GPIO bit will clear every other GPIO bit (but only sometimes after a suspend). The workaround described is obvious and simple; do a read-modify-write. This patch does that, and documents why we're doing it.

2010-12-02reiserfs: don't acquire lock recursively in reiserfs_acl_chmodFrederic Weisbecker1-2/+4
reiserfs_acl_chmod() can be called by reiserfs_set_attr() and then take the reiserfs lock a second time. Thereafter it may call journal_begin() that definitely requires the lock not to be nested in order to release it before taking the journal mutex because the reiserfs lock depends on the journal mutex already. So, aviod nesting the lock in reiserfs_acl_chmod().

It's not useful to build LED triggers when there's no LEDs that can be triggered by them.

2010-12-02xen: fix MSI setup and teardown for PV on HVM guestsStefano Stabellini3-15/+43
When remapping MSIs into pirqs for PV on HVM guests, qemu is responsible for doing the actual mapping and unmapping. We only give qemu the desired pirq number when we ask to do the mapping the first time, after that we should be reading back the pirq number from qemu every time we want to re-enable the MSI. This fixes a bug in xen_hvm_setup_msi_irqs that manifests itself when trying to enable the same MSI for the second time: the old MSI to pirq mapping is still valid at this point but xen_hvm_setup_msi_irqs would try to assign a new pirq anyway. A simple way to reproduce this bug is to assign an MSI capable network card to a PV on HVM guest, if the user brings down the corresponding ethernet interface and up again, Linux would fail to enable MSIs on the device.

This fixes find_unbound_pirq that otherwise would return a number starting from nr_irqs that might very well be out of range in Xen. The symptom of this bug is that when you passthrough an MSI capable pci device to a PV on HVM guest, Linux would fail to enable MSIs on the device.

2010-12-01xfs: avoid moving stale inodes in the AILDave Chinner1-6/+25
When an inode has been marked stale because the cluster is being freed, we don't want to (re-)insert this inode into the AIL. There is a race condition where the cluster buffer may be unpinned before the inode is inserted into the AIL during transaction committed processing. If the buffer is unpinned before the inode item has been committed and inserted, then it is possible for the buffer to be released and hence processthe stale inode callbacks before the inode is inserted into the AIL. In this case, we then insert a clean, stale inode into the AIL which will never get removed by an IO completion. It will, however, get reclaimed and that triggers an assert in xfs_inode_free() complaining about freeing an inode still in the AIL. This race can be avoided by not moving stale inodes forward in the AIL during transaction commit completion processing. This closes the race condition by ensuring we never insert clean stale inodes into the AIL. It is safe to do this because a dirty stale inode, by definition, must already be in the AIL.

2010-12-01xfs: delayed alloc blocks beyond EOF are valid after writebackDave Chinner2-2/+20
There is an assumption in the parts of XFS that flushing a dirty file will make all the delayed allocation blocks disappear from an inode. That is, that after calling xfs_flush_pages() then ip->i_delayed_blks will be zero. This is an invalid assumption as we may have specualtive preallocation beyond EOF and they are recorded in ip->i_delayed_blks. A flush of the dirty pages of an inode will not change the state of these blocks beyond EOF, so a non-zero deeelalloc block count after a flush is valid. The bmap code has an invalid ASSERT() that needs to be removed, and the swapext code has a bug in that while it swaps the data forks around, it fails to swap the i_delayed_blks counter associated with the fork and hence can get the block accounting wrong.

2010-12-01xfs: push stale, pinned buffers on trylock failuresDave Chinner1-19/+16
As reported by Nick Piggin, XFS is suffering from long pauses under highly concurrent workloads when hosted on ramdisks. The problem is that an inode buffer is stuck in the pinned state in memory and as a result either the inode buffer or one of the inodes within the buffer is stopping the tail of the log from being moved forward. The system remains in this state until a periodic log force issued by xfssyncd causes the buffer to be unpinned. The main problem is that these are stale buffers, and are hence held locked until the transaction/checkpoint that marked them state has been committed to disk. When the filesystem gets into this state, only the xfssyncd can cause the async transactions to be committed to disk and hence unpin the inode buffer. This problem was encountered when scaling the busy extent list, but only the blocking lock interface was fixed to solve the problem. Extend the same fix to the buffer trylock operations - if we fail to lock a pinned, stale buffer, then force the log immediately so that when the next attempt to lock it comes around, it will have been unpinned.

2010-12-01xfs: fix failed write truncation handling.Dave Chinner3-54/+121
Since the move to the new truncate sequence we call xfs_setattr to truncate down excessively instanciated blocks. As shown by the testcase in kernel.org BZ #22452 that doesn't work too well. Due to the confusion of the internal inode size, and the VFS inode i_size it zeroes data that it shouldn't. But full blown truncate seems like overkill here. We only instanciate delayed allocations in the write path, and given that we never released the iolock we can't have converted them to real allocations yet either. The only nasty case is pre-existing preallocation which we need to skip. We already do this for page discard during writeback, so make the delayed allocation block punching a generic function and call it from the failed write path as well as xfs_aops_discard_page. The callers are responsible for ensuring that partial blocks are not truncated away, and that they hold the ilock. Based on a fix originally from Christoph Hellwig. This version used filesystem blocks as the range unit. Signed-off-by: Dave Chinner <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>
