From: Joe Perches Date: Wed, 19 Jun 2013 19:15:53 +0000 (-0700) Subject: treewide: Add __GFP_NOWARN to k.alloc calls with v.alloc fallbacks X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8be04b9374e59923fa337766aaa74151b95b7099;p=linux-beck.git treewide: Add __GFP_NOWARN to k.alloc calls with v.alloc fallbacks Don't emit OOM warnings when k.alloc calls fail when there there is a v.alloc immediately afterwards. Converted a kmalloc/vmalloc with memset to kzalloc/vzalloc.
