[Ocfs2-devel] [PATCH] dlm: make dlm_posix_lock comply with posix file lock semanteme
Posix file lock semanteme expects that waiting processes that request
a conflicting lock on file can be interrputed by signals like SIGALRM.
But, dlm_posix_lock puts waiting process into "Disk Sleep" status.
This failed ocfs2 test suits for posix file lock.
Replacing wait_event_killable with wait_event_interruptible can fix
this issue.
