Fabian Frederick ed3ad79f87 fs/ufs/super.c: fix potential race condition ... Let locking subsystem decide on mutex management. As reported by Andrew Morton this patch fixes a bug: : lock_ufs() is assuming that on non-preempt uniprocessor, the calling : code will run atomically up to the matching unlock_ufs(). : : But that isn't true. The very first site I looked at (ufs_frag_map) : does sb_bread() under lock_ufs(). And sb_bread() will call schedule(), : very commonly. : : The ->mutex_owner stuff is a bit hacky but should work OK.
