From 28daf4fae8693d4a285123494899fe01950cba50 Mon Sep 17 00:00:00 2001 From: Zheng Liu Date: Fri, 19 Apr 2013 17:49:23 -0400 Subject: [PATCH] jbd2: use kmem_cache_zalloc instead of kmem_cache_alloc/memset The jbd2_alloc_handle() function is only called by new_handle(). So this commit uses kmem_cache_zalloc() instead of kmem_cache_alloc()/memset().
