From: Michal Hocko Date: Fri, 24 Jun 2016 21:49:09 +0000 (-0700) Subject: score: get rid of superfluous __GFP_REPEAT X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a4135b93898fe38ea4136c6b03b29b746e08c83a;p=openwrt%2Fstaging%2Fblogic.git score: get rid of superfluous __GFP_REPEAT __GFP_REPEAT has a rather weak semantic but since it has been introduced around 2.6.12 it has been ignored for low order allocations. pte_alloc_one{_kernel} allocate PTE_ORDER which is 0. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
