From a8c0f9a41f88da703ade33f9c1626a55c786e8bb Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Sat, 25 Mar 2006 03:06:42 -0800 Subject: [PATCH] slab: introduce kmem_cache_zalloc allocator Introduce a memory-zeroing variant of kmem_cache_alloc. The allocator already exits in XFS and there are potential users for it so this patch makes the allocator available for the general public.
