Subject: [PATCH 1/2] NFSv4.1/pnfs: Ensure we send layoutcommit before return-on-close
Date: Fri, 27 Mar 2015 13:07:53 -0400	[thread overview]
Message-ID: <1427476074-14736-1-git-send-email-trond.myklebust@primarydata.com> (raw)

We must not send a close or delegreturn that would result in a
return-on-close of the layout without ensuring that we've also
sent the necessary layoutcommit.
