From 1255a8f36cb16a02540bdad91c0bc0971b9fb429 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 6 Mar 2012 14:35:16 -0500 Subject: [PATCH] nfsd4: don't set cl_firststate on first reclaim in 4.1 case We set cl_firststate when we first decide that a client will be permitted to reclaim state on next boot. This happens: - for new 4.0 clients, when they confirm their first open - for returning 4.0 clients, when they reclaim their first open - for 4.1+ clients, when they perform reclaim_complete We also use cl_firststate to decide whether a reclaim_complete has already been performed, in the 4.1+ case. We were setting it on 4.1 open reclaims, which caused spurious COMPLETE_ALREADY errors on RECLAIM_COMPLETE from an nfs4.1 client with anything to reclaim. Reported-by: Jeff Layton Signed-off-by: J.
