Subject: [PATCH 0/4] cleancache: remove limit on the number of cleancache enabled filesystems
Date: Sun, 22 Feb 2015 21:31:51 +0300 [thread overview]
Message-ID: <cover.1424628280.git.vdavydov@parallels.com> (raw)
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
