From db24b3b4b2a510ad0face05aec1c5bfbe89050bb Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 30 Jun 2014 11:48:36 -0400 Subject: [PATCH] nfsd: declare v4.1+ openowners confirmed on creation There's no need to confirm an openowner in v4.1 and above, so we can go ahead and set NFS4_OO_CONFIRMED when we create openowners in those versions. This will also be necessary when we remove the client_mutex, as it'll be possible for two concurrent opens to race in versions >4.0.
