Subject: [PATCH V4 7/8] Cleancache: ext4 hook for cleancache
Date: Mon, 30 Aug 2010 15:33:34 -0700 [thread overview]
Message-ID: <20100830223334.GA1361@ca-server1.us.oracle.com> (raw)
[PATCH V4 7/8] Cleancache: ext4 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 ext4,
all other cleancache hooks are in the VFS layer including
the matching cleancache_flush_fs hook which must be
called on unmount.
