Subject: [PATCH v3 02/21] xprtrdma: Fix an frwr_map recovery nit
Date: Wed, 24 Apr 2019 09:39:00 -0400
Message-ID: <20190424133900.5077.23949.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20190424133516.5077.67283.stgit@manet.1015granger.net>

After a DMA map failure in frwr_map, mark the MR so that recycling
won't attempt to DMA unmap it.

Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
Fixes: e2f34e26710b ("xprtrdma: Yet another double DMA-unmap")
