Subject: [PATCH 10/19] score: get rid of superfluous __GFP_REPEAT
Date: Mon, 11 Apr 2016 13:08:03 +0200 [thread overview]
Message-ID: <1460372892-8157-11-git-send-email-mhocko@kernel.org> (raw)
In-Reply-To: <1460372892-8157-1-git-send-email-mhocko@kernel.org>
From: Michal Hocko <mhocko@suse.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.
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.
