*	[PATCH] Skip check for mandatory locks when unlocking	Sachin Prabhu	2010-03-17	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \|	ocfs2_lock() will skip locks on file which has mode set to 02666. This is a problem in cases where the mode of the file is changed after a process has obtained a lock on the file. ocfs2_lock() should skip the check for mandatory locks when unlocking a file.

*	ocfs2: POSIX file locks support	Mark Fasheh	2008-10-13	1	-0/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This is actually pretty easy since fs/dlm already handles the bulk of the work. The Ocfs2 userspace cluster stack module already uses fs/dlm as the underlying lock manager, so I only had to add the right calls. Cluster-aware POSIX locks ("plocks") can be turned off by the same means at UNIX locks - mount with 'noflocks', or create a local-only Ocfs2 volume. Internally, the file system uses two sets of file_operations, depending on whether cluster aware plocks is required. This turns out to be easier than implementing local-only versions of ->lock.

*	[PATCH 2/2] ocfs2: cluster aware flock()	Mark Fasheh	2008-01-25	1	-0/+125
	Hook up ocfs2_flock(), using the new flock lock type in dlmglue.c. A new mount option, "localflocks" is added so that users can revert to old functionality as need be. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
