Subject: [PATCH][net-next] svcrdma: fix an incorrect check on -E2BIG and -EINVAL
Date: Thu, 13 Jul 2017 18:51:15 +0100	[thread overview]
Message-ID: <20170713175115.9044-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

The current check will always be true and will always jump to
err1, this looks dubious to me. I believe && should be used
instead of ||.

Detected by CoverityScan, CID#1450120 ("Logically Dead Code")

Fixes: 107c1d0a991a ("svcrdma: Avoid Send Queue overflow")
