Subject: [Ocfs2-devel] [PATCH V2 7/7] Cleancache (was Transcendent Memory): ocfs2 hook
Date: Fri, 28 May 2010 17:38:47 -0000 [thread overview]
Message-ID: <20100528173731.GA20227@ca-server1.us.oracle.com> (raw)
[PATCH V2 7/7] Cleancache (was Transcendent Memory): ocfs2 hook
Filesystems must explicitly enable cleancache. Ocfs2 is
currently the only user of the clustered filesystem
interface but nevertheless, the cleancache hooks in the
VFS layer are sufficient for ocfs2.
