2011-06-13ALSA: hda - Fix wrong auto-mute type for Acer Aspire-oneTakashi Iwai1-2/+1
The auto-mute setup for Acer Aspire-one with ALC268 was set wrongly during the clean-up of auto-mute function. Fixed now. Tested-by: Borislav Petkov <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
2011-06-12HID: hid-multitouch: fix broken eGalaxBenjamin Tissoires1-18/+39
Since the inclusion of eGalax devices in 2.6.39, I've got some bug reports for 480d and other devices. The problem lies in the reports descriptors: eGalax supports both pen and fingers, and so the reports descriptors contained both. But hid-multitouch relies on them to detect the last item in each field to send the multitouch events. In 480d, the last item is not Y as it should but Pressure. That means that the fields are not aligned and X,Y are at 0,0 (the other touch coordinates of the report). With this patch, the detection is made only when the field ContactID has been detected inside the collection. There is still a problem with the detections of the range as stylus and fingers may not have the same min/max, but it's a start.

2011-06-12Delay struct net freeing while there's a sysfs instance refering to itAl Viro8-72/+55
* new refcount in struct net, controlling actual freeing of the memory * new method in kobj_ns_type_operations (->drop_ns()) * ->current_ns() semantics change - it's supposed to be followed by corresponding ->drop_ns(). For struct net in case of CONFIG_NET_NS it bumps the new refcount; net_drop_ns() decrements it and calls net_free() if the last reference has been dropped. Method renamed to ->grab_current_ns(). * old net_free() callers call net_drop_ns() instead. * sysfs_exit_ns() is gone, along with a large part of callchain leading to it; now that the references stored in ->ns[...] stay valid we do not need to hunt them down and replace them with NULL. That fixes problems in sysfs_lookup() and sysfs_readdir(), along with getting rid of sb->s_instances abuse. Note that struct net *shutdown* logics has not changed - net_cleanup() is called exactly when it used to be called. The only thing postponed by having a sysfs instance refering to that struct net is actual freeing of memory occupied by struct net. Signed-off-by: Al Viro <[email protected]>
2011-06-12afs: fix sget() races, close leak on umountAl Viro1-41/+32
* set ->s_fs_info in set() callback passed to sget() * allocate the thing and set it up enough for afs_test_super() before making it visible * have it freed in ->kill_sb() (current tree simply leaks it) * have ->put_super() leave ->s_fs_info->volume alone; it's too early for dropping it; do that from ->kill_sb() after having called kill_anon_super().

2011-06-12ubifs: fix sget racesAl Viro1-24/+30
* allocate ubifs_info in ->mount(), fill it enough for sb_test() and set ->s_fs_info to it in set() callback passed to sget(). * do *not* free it in ->put_super(); do that in ->kill_sb() after we'd done kill_anon_super(). * don't free it in ubifs_fill_super() either - deactivate_locked_super() done by caller when ubifs_fill_super() returns an error will take care of that sucker. * get rid of kludge with passing ubi to ubifs_fill_super() in ->s_fs_info; we only need it in alloc_ubifs_info(), so ubifs_fill_super() will need only ubifs_info. Which it will find in ->s_fs_info just fine, no need to reassign anything... As the result, sb_test() becomes safe to apply to all superblocks that can be found by sget() (and a kludge with temporary use of ->s_fs_info to store a pointer to very different structure goes away).

2011-06-11vlan: Fix the ingress VLAN_FLAG_REORDER_HDR checkJiri Pirko4-31/+61
Testing of VLAN_FLAG_REORDER_HDR does not belong in vlan_untag but rather in vlan_do_receive. Otherwise the vlan header will not be properly put on the packet in the case of vlan header accelleration. As we remove the check from vlan_check_reorder_header rename it vlan_reorder_header to keep the naming clean. Fix up the skb->pkt_type early so we don't look at the packet after adding the vlan tag, which guarantees we don't goof and look at the wrong field. Use a simple if statement instead of a complicated switch statement to decided that we need to increment rx_stats for a multicast packet. Hopefully at somepoint we will just declare the case where VLAN_FLAG_REORDER_HDR is cleared as unsupported and remove the code. Until then this keeps it working correctly. Signed-off-by: Eric W.

2011-06-10btrfs: remove 64bit alignment padding to allow extent_buffer to fit into one ↵richard kennedy1-1/+1
fewer cacheline Reorder extent_buffer to remove 8 bytes of alignment padding on 64 bit builds. This shrinks its size to 128 bytes allowing it to fit into one fewer cache lines and allows more objects per slab in its kmem_cache. slabinfo extent_buffer reports :- before:- Sizes (bytes) Slabs ---------------------------------- Object : 136 Total : 123 SlabObj: 136 Full : 121 SlabSiz: 4096 Partial: 0 Loss : 0 CpuSlab: 2 Align : 8 Objects: 30 after :- Object : 128 Total : 4 SlabObj: 128 Full : 2 SlabSiz: 4096 Partial: 0 Loss : 0 CpuSlab: 2 Align : 8 Objects: 32 Signed-off-by: Richard Kennedy <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2011-06-10Btrfs: clear current->journal_info on async transaction commitSage Weil1-1/+4
Normally current->jouranl_info is cleared by commit_transaction. For an async snap or subvol creation, though, it runs in a work queue. Clear it in btrfs_commit_transaction_async() to avoid leaking a non-NULL journal_info when we return to userspace. When the actual commit runs in the other thread it won't care that it's current->journal_info is already NULL.

2011-06-10Btrfs: make sure to recheck for bitmaps in clustersChris Mason1-4/+5
Josef recently changed the free extent cache to look in the block group cluster for any bitmaps before trying to add a new bitmap for the same offset. This avoids BUG_ON()s due covering duplicate ranges. But it didn't go quite far enough. A given free range might span between one or more bitmaps or free space entries. The code has looping to cover this, but it doesn't check for clustered bitmaps every time. This shuffles our gotos to check for a bitmap in the cluster for every new bitmap entry we try to add.
