Subject: [PATCH 02/16] nfsd4: combine nfs4_rpc_args and nfsd4_cb_sequence
Date: Thu, 30 Sep 2010 12:18:59 -0400 [thread overview]
Message-ID: <1285863553-8945-3-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1285863553-8945-1-git-send-email-bfields@redhat.com>
From: J. Bruce Fields <bfields@citi.umich.edu>
These two structs don't really need to be distinct as far as I can tell.
Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
