Next: [PATCH V3 7/8] Cleancache: ext4 hook for cleancache
From: Dan Magenheimer on 21 Jun 2010 19:30 [PATCH V3 5/8] Cleancache: ext3 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. For ext3, all other cleancache hooks are in the VFS layer including the matching cleancache_flush_fs hook which must be called on unmount.
