Date: Mon, 30 May 2016 11:14:58 +0200 From: Michal Hocko <mhocko@...nel.org> To: Andrew Morton <akpm@...ux-foundation.org> Cc: <linux-mm@...ck.org>, LKML <linux-kernel@...r.kernel.org>, Michal Hocko <mhocko@...e.com>, Guan Xuetao <gxt@...c.pku.edu.cn>, linux-arch@...r.kernel.org Subject: [PATCH 16/17] unicore32: get rid of superfluous __GFP_REPEAT From: Michal Hocko <mhocko@...e.com> __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. PGALLOC_GFP uses __GFP_REPEAT but it is only used in pte_alloc_one, pte_alloc_one_kernel which does order-0 request. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
