Subject: [PATCH 4.9 19/22] ntb: ntb_perf missing dmaengine_unmap_put
Date: Tue, 21 Feb 2017 14:03:33 +0100 [thread overview]
Message-ID: <20170221130219.715824705@linuxfoundation.org> (raw)
In-Reply-To: <20170221130218.888428471@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dave Jiang <dave.jiang@intel.com>
commit 9644347c5240d0ee3ba7472ef332aaa4ff4db398 upstream.
In the normal I/O execution path, ntb_perf is missing a call to
dmaengine_unmap_put() after submission. That causes us to leak
unmap objects.
