Subject: [PATCH 18/19] pnfs: Don't call commit on failed layoutget-on-open
Date: Wed, 30 May 2018 14:05:52 -0400
Message-ID: <20180530180553.38769-19-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20180530180553.38769-18-trond.myklebust@hammerspace.com>
If the layoutget on open call failed, we can't really commit the inode,
so don't bother calling it.
