From 94f6030ca792c57422f04a73e7a872d8325946d3 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 17 Jul 2007 04:03:29 -0700 Subject: Slab allocators: Replace explicit zeroing with __GFP_ZERO kmalloc_node() and kmem_cache_alloc_node() were not available in a zeroing variant in the past. But with __GFP_ZERO it is possible now to do zeroing while allocating. Use __GFP_ZERO to remove the explicit clearing of memory via memset whereever we can.
