346dbf1b - dm-cache: fix warnings about duplicate slab caches

Mon, 11 Nov 2024 15:51:02 +0000

dm-cache: fix warnings about duplicate slab cachesThe commit 4c39529663b9 adds a warning about duplicate cache names ifCONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-cachecode.The dm-cache code allocates a slab cache for each device. This commitchanges it to allocate just one slab cache in the module init function.Signed-off-by: Mikulas Patocka Fixes: 4c39529663b9 ("slab: Warn on duplicate cache names when DEBUG_VM=y") List of files: /linux-6.15/drivers/md/dm-cache-background-tracker.h

b29d4986 - dm cache: significant rework to leverage dm-bio-prison-v2

Thu, 15 Dec 2016 09:57:31 +0000

dm cache: significant rework to leverage dm-bio-prison-v2The cache policy interfaces have been updated to work well with the newbio-prison v2 interface's ability to queue work immediately (promotion,demotion, etc) -- overriding benefit being reduced latency on processingIO through the cache. Previously such work would be left for the DMcache core to queue on various lists and then process in batches later-- this caused a serious delay in latency for IO driven by the cache.The background tracker code was factored out so that all cache policiescan make use of it.Also, the "cleaner" policy has been removed and is now a variant of thesmq policy that simply disallows migrations.Signed-off-by: Joe Thornber Signed-off-by: Mike Snitzer List of files: /linux-6.15/drivers/md/dm-cache-background-tracker.h
