From 8be04b9374e59923fa337766aaa74151b95b7099 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Wed, 19 Jun 2013 12:15:53 -0700 Subject: 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.
