[PATCH] mm-slab: allocate kmem_cache with __GFP_REPEAT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
