2011-07-25ipc/sem.c: fix race with concurrent semtimedop() timeouts and IPC_RMIDManfred Spraul
If a semaphore array is removed and in parallel a sleeping task is woken up (signal or timeout, does not matter), then the woken up task does not wait until wake_up_sem_queue_do() is completed. This will cause crashes, because wake_up_sem_queue_do() will read from a stale pointer. The fix is simple: Regardless of anything, always call get_queue_result(). This function waits until wake_up_sem_queue_do() has finished it's task.

2011-07-25vfs: make gcc generate more obvious code for acl permission checkingLinus Torvalds
The "fsuid is the inode owner" case is not necessarily always the likely case, but it's the case that doesn't do anything odd and that we want in straight-line code. Make gcc not generate random "jump around for the fun of it" code. This just helps me read profiles. That thing is one of the hottest parts of the whole pathname lookup.

2011-07-26md/raid5: move stripe_head_state and more code into handle_stripe.NeilBrown
By defining the 'stripe_head_state' in 'handle_stripe', we can move some common code out of handle_stripe[56]() and into handle_stripe. The means that all accesses for stripe_head_state in handle_stripe[56] need to be 's->' instead of 's.', but the compiler should inline those functions and just use a direct stack reference, and future patches while hoist most of this code up into handle_stripe() so we will revert to "s.".

2011-07-26md/raid5: unify stripe_head_state and r6_stateNeilBrown
'struct stripe_head_state' stores state about the 'current' stripe that is passed around while handling the stripe. For RAID6 there is an extension structure: r6_state, which is also passed around. There is no value in keeping these separate, so move the fields from the latter into the former. This means that all code now needs to treat s->failed_num as an small array, but this is a small cost.

2011-07-26md/raid5: replace sh->lock with an 'active' flag.NeilBrown
sh->lock is now mainly used to ensure that two threads aren't running in the locked part of handle_stripe[56] at the same time. That can more neatly be achieved with an 'active' flag which we set while running handle_stripe. If we find the flag is set, we simply requeue the stripe for later by setting STRIPE_HANDLE. For safety we take ->device_lock while examining the state of the stripe and creating a summary in 'stripe_head_state / r6_state'. This possibly isn't needed but as shared fields like ->toread, ->towrite are checked it is safer for now at least. We leave the label after the old 'unlock' called "unlock" because it will disappear in a few patches, so renaming seems pointless. This leaves the stripe 'locked' for longer as we clear STRIPE_ACTIVE later, but that is not a problem. Signed-off-by: NeilBrown <neilb@suse.de> Reviewed-by: Namhyung Kim <namhyung@gmail.com>

This is the start of a series of patches to remove sh->lock. sync_request takes sh->lock before setting STRIPE_SYNCING to ensure there is no race with testing it in handle_stripe[56]. Instead, use a new flag STRIPE_SYNC_REQUESTED and test it early in handle_stripe[56] (after getting the same lock) and perform the same set/clear operations if it was set.

2011-07-25nfs: don't use d_move in nfs_async_rename_doneJeff Layton
If the task that initiated the sillyrename ends up being killed by a fatal signal, then it will eventually return back to userspace and end up releasing the i_mutex. d_move however needs to be done while holding the i_mutex. Instead of using d_move here, just unhash the old and new dentries to prevent them from being found by lookups. With this change though, the dentries are now incorrect post-rename and do not reflect the actual name of the file on the server. I'm proceeding under the assumption that since they are unhashed that this isn't really a problem. In order for the sillydelete to still work though, the dname must be copied earlier when setting up the sillydelete info, and the name must be recopied if the sillydelete info has to be moved to a new dentry.
