Subject: [PATCH 4.4 15/43] iw_cxgb4: correctly enforce the max reg_mr depth
Date: Mon, 16 Jul 2018 09:36:20 +0200 [thread overview]
Message-ID: <20180716073513.467557049@linuxfoundation.org> (raw)
In-Reply-To: <20180716073511.796555857@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steve Wise <swise@opengridcomputing.com>
commit 7b72717a20bba8bdd01b14c0460be7d15061cd6b upstream.
The code was mistakenly using the length of the page array memory instead
of the depth of the page array.
This would cause MR creation to fail in some cases.
Fixes: 8376b86de7d3 ("iw_cxgb4: Support the new memory registration API")
