Subject: [PATCH] staging: android: ion: Use low_order_gfp_flags for smaller allocations
Date:   Tue, 12 Feb 2019 15:09:26 +0800
Message-Id: <1549955366-19930-1-git-send-email-jing.xia@unisoc.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

gfp_flags is always set high_order_gfp_flags even if allocations of
order 0 are made.But for smaller allocations, the system should be able
to reclaim some memory.
