Subject: [PATCH 0/4] cleancache: remove limit on the number of cleancache enabled filesystems

Hi,

Currently, maximal number of cleancache enabled filesystems equals 32,
which is insufficient nowadays, because a Linux host can have hundreds
of containers on board, each of which might want its own filesystem.
This patch set targets at removing this limitation - see patch 4 for
more details. Patches 1-3 prepare the code for this change.

Thanks,

Vladimir Davydov (4):
  ocfs2: copy fs uuid to superblock
  cleancache: zap uuid arg of cleancache_init_shared_fs
  cleancache: forbid overriding cleancache_ops
  cleancache: remove limit on the number of cleancache enabled
    filesystems
