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 Documentation/vm/cleancache.txt | 4 +- drivers/xen/tmem.c | 16 ++- fs/ocfs2/super.c | 4 +- fs/super.c | 2 +- include/linux/cleancache.h | 13 +- mm/cleancache.c | 270 +++++++++++---------------------------- 6 files changed, 94 insertions(+), 215 deletions(-) -- 1.7.10.4 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
