From e162b2f835eeda0d255bd463753b5eb823735205 Mon Sep 17 00:00:00 2001 From: Zheng Liu Date: Fri, 12 Apr 2013 02:24:06 +0000 Subject: [PATCH] jbd: use kmem_cache_zalloc instead of kmem_cache_alloc/memset Now jbd_alloc_handle is only called by new_handle. So this commit uses kmem_cache_zalloc instead of kmem_cache_alloc/memset.
