Subject: [PATCH V4 8/8] Cleancache: ocfs2 hook for cleancache
Date: Mon, 30 Aug 2010 15:34:04 -0700 [thread overview]
Message-ID: <20100830223404.GA1381@ca-server1.us.oracle.com> (raw)
[PATCH V4 8/8] Cleancache: ocfs2 hook for cleancache
Filesystems must explicitly enable cleancache by calling
cleancache_init_fs anytime a instance of the filesystem
is mounted and must save the returned poolid. Ocfs2 is
currently the only user of the clustered filesystem
interface but nevertheless, the cleancache hooks in the
VFS layer are sufficient for ocfs2 including
the matching cleancache_flush_fs hook which must be
called on unmount.
