Subject: [PATCH v6 14/29] NFSv4.1: FREE_STATEID can be asynchronous
Date: Tue, 20 Sep 2016 12:55:56 -0400 [thread overview]
Message-ID: <1474390571-17106-15-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1474390571-17106-14-git-send-email-trond.myklebust@primarydata.com>
Nothing should need to be serialised with FREE_STATEID on the client,
so let's make the RPC call always asynchronous. Also constify the
stateid argument.
