Subject: [PATCH v5 12/25] NFSv4.1: FREE_STATEID can be asynchronous
Date: Sat, 17 Sep 2016 01:13:20 -0400 [thread overview]
Message-ID: <1474089213-104014-13-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1474089213-104014-12-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.
