Subject: [PATCH v3 18/38] nfsd: Migrate the stateid reference into nfs4_preprocess_seqid_op
Date: Tue, 29 Jul 2014 21:34:23 -0400	[thread overview]
Message-ID: <1406684083-19736-19-git-send-email-jlayton@primarydata.com> (raw)
In-Reply-To: <1406684083-19736-1-git-send-email-jlayton@primarydata.com>

From: Trond Myklebust <trond.myklebust@primarydata.com>

Allow nfs4_preprocess_seqid_op to take the stateid reference, instead
of having all the callers do so.
