ext3: add cleancache support
This fifth patch of eight in this cleancache series "opts-in"
cleancache for ext3. Filesystems must explicitly enable
cleancache by calling cleancache_init_fs anytime an instance
of the filesystem is mounted. For ext3, all other cleancache
hooks are in the VFS layer including the matching cleancache_flush_fs
hook which must be called on unmount.
Details and a FAQ can be found in Documentation/vm/cleancache.txt
[v6-v8: no changes]
[v5: jeremy@goop.org: simplify init hook and any future fs init changes]
