From: Marek Szyprowski Date: Fri, 17 Jan 2014 08:46:56 +0000 (+0100) Subject: staging: lustre: fix GFP_ATOMIC macro usage X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1ebf5b72dc8bfbe5e7866ee1a2eb935fc7d050e6;p=linux-beck.git staging: lustre: fix GFP_ATOMIC macro usage GFP_ATOMIC is not a single gfp flag, but a macro which expands to the other flags and LACK of __GFP_WAIT flag. To check if caller wanted to perform an atomic allocation, the code must test __GFP_WAIT flag presence.
