Subject: [PATCH 21/27] SUNRPC: Don't reset the request 'bytes_sent' counter when releasing XPRT_LOCK
Date: Mon,  3 Sep 2018 11:29:30 -0400	[thread overview]
Message-ID: <20180903152936.24325-22-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20180903152936.24325-21-trond.myklebust@hammerspace.com>

If the request is still on the queue, this will be incorrect behaviour.
