[PATCH 03/13] RFC: pnfsd, pnfs: protocol level pnfs constants

Fred Isaman

From: The pNFS Team <linux-nfs@vger.kernel.org>

Use only layoutreturn constant for both returns and recalls.
(return_* works better for recall_type rather the other way around)

Signed-off-by: TBD - melding/reorganization of several patches
