Subject: [PATCH] mm-slab: allocate kmem_cache with __GFP_REPEAT
Date: Wed, 20 Jul 2011 16:16:12 +0400 [thread overview]
Message-ID: <20110720121612.28888.38970.stgit@localhost6> (raw)
Order of sizeof(struct kmem_cache) can be bigger than PAGE_ALLOC_COSTLY_ORDER,
thus there is a good chance of unsuccessful allocation.
With __GFP_REPEAT buddy-allocator will reclaim/compact memory more aggressively.
