[PATCH V3 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.
