Subject: [PATCH 2/1] xfs: fix xfs_error_get_cfg for negative errnos
Date: Fri, 8 Jul 2016 23:26:13 -0500
Message-ID: <c803d93a-ad47-faf1-5288-62da612646a9@sandeen.net> (raw)
In-Reply-To: <9810c6bf-9fd7-bf41-13ab-a96bec861457@redhat.com>

Fix up a couple places where flag manipulation is unclear.

In the first case we clear XBF_ASYNC and then immediately
reset it.

In the 2nd case we are at a point in the function where the
buffer must already be async, so no need to reset it.

Add consistent spacing around the " | " while we're at it.
