Subject: [PATCH 4.4 12/25] async_pq_val: fix DMA memory leak
Date: Fri, 21 Oct 2016 11:16:03 +0200 [thread overview]

------------------
From: Justin Maggard <jmaggard10@gmail.com>
commit c84750906b4818d4929fbf73a4ae6c113b94f52b upstream.
Add missing dmaengine_unmap_put(), so we don't OOM during RAID6 sync.
