| 2013-04-30 | mm: cleancache: clean up cleancache_enabled | Bob Liu | 1 | -1/+1 | |
| cleancache_ops is used to decide whether backend is registered. So now cleancache_enabled is always true if defined CONFIG_CLEANCACHE.

| 2013-04-30 | cleancache: Make cleancache_init use a pointer for the ops | Konrad Rzeszutek Wilk | 1 | -1/+1 | |
| Instead of using a backend_registered to determine whether a backend is enabled. This allows us to remove the backend_register check and just do 'if (cleancache_ops)' [v1: Rebase on top of b97c4b430b0a (ramster->zcache move] Signed-off-by: Konrad Rzeszutek Wilk <[email protected]> Signed-off-by: Bob Liu <[email protected]> Cc: Wanpeng Li <[email protected]> Cc: Andor Daam <[email protected]> Cc: Dan Magenheimer <[email protected]> Cc: Florian Schmaus <[email protected]> Cc: Minchan Kim <[email protected]> Cc: Stefan Hengelein <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]> | |||||
| 2012-01-23 | mm: zcache/tmem/cleancache: s/flush/invalidate/ | Dan Magenheimer | 1 | -8/+3 | |
| Complete the renaming from "flush" to "invalidate" across both tmem frontends (cleancache and frontswap) and both tmem backends (Xen and zcache), as required by akpm. This change is completely cosmetic.

| 2012-01-23 | mm: cleancache: s/flush/invalidate/ | Dan Magenheimer | 1 | -9/+14 | |
| Per akpm suggestions alter the use of the term flush to be invalidate. The next patch will do this across all MM. This change is completely cosmetic.

| 2011-05-26 | mm: cleancache core ops functions and config | Dan Magenheimer | 1 | -0/+122 | |
| This third patch of eight in this cleancache series provides the core code for cleancache that interfaces between the hooks in VFS and individual filesystems and a cleancache backend. It also includes build and config patches. Two new files are added: mm/cleancache.c and include/linux/cleancache.h. Note that CONFIG_CLEANCACHE can default to on; in systems that do not provide a cleancache backend, all hooks devolve to a simple check of a global enable flag, so performance impact should be negligible but can be reduced to zero impact if config'ed off. However for this first commit, it defaults to off.
