From 1f9061d27d3d2028805549c4a306324a48209057 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Fri, 15 Mar 2013 07:23:58 +0000 Subject: drivers:net: dma_alloc_coherent: use __GFP_ZERO instead of memset(, 0) Reduce the number of calls required to alloc a zeroed block of memory. Trivially reduces overall object size. Other changes around these removals o Neaten call argument alignment o Remove an unnecessary OOM message after dma_alloc_coherent failure o Remove unnecessary gfp_t stack variable Signed-off-by: Joe Perches Signed-off-by: David S.
