fs/locks.c: prepare for BKL removal

2010-10-05T09:02:04Z

This prepares the removal of the big kernel lock from the file locking code. We still use the BKL as long as fs/lockd uses it and ceph might sleep, but we can flip the definition to a private spinlock as soon as that's done. All users outside of fs/lockd get converted to use lock_flocks() instead of lock_kernel() where appropriate. Based on an earlier patch to use a spinlock from Matthew Wilcox, who has attempted this a few times before, the earliest patch from over 10 years ago turned it into a semaphore, which ended up being slower than the BKL and was subsequently reverted. Someone should do some serious performance testing when this becomes a spinlock, since this has caused problems before. Using a spinlock should be at least as good as the BKL in theory, but who knows... Signed-off-by: Arnd Bergmann Acked-by: Matthew Wilcox Cc: Christoph Hellwig Cc: Trond Myklebust Cc: "J.

The __mandatory_lock(inode) macro makes the same check, but makes the code more readable. Signed-off-by: Pavel Emelyanov Cc: David Howells Signed-off-by: Andrew Morton

AFS: fix file locking

2007-07-31T22:39:40Z

Fix file locking for AFS: (*) Start the lock manager thread under a mutex to avoid a race. (*) Made the locking non-fair: New readlocks will jump pending writelocks if there's a readlock currently granted on a file. This makes the behaviour similar to Linux's VFS locking.
