From fd9110113c434562c287f222cb4e30befb15ecdd Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 29 Jul 2014 21:34:24 -0400 Subject: [PATCH] nfsd: Migrate the stateid reference into nfs4_lookup_stateid() Allow nfs4_lookup_stateid to take the stateid reference, instead of having all the callers do so.
