From ba5378b66f5eb20e464796c5b088c0961fb5f618 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Fri, 30 May 2014 09:09:28 -0400 Subject: nfsd: fix setting of NFS4_OO_CONFIRMED in nfsd4_open In the NFS4_OPEN_CLAIM_PREVIOUS case, we should only mark it confirmed if the nfs4_check_open_reclaim check succeeds. In the NFS4_OPEN_CLAIM_DELEG_PREV_FH and NFS4_OPEN_CLAIM_DELEGATE_PREV cases, I see no point in declaring the openowner confirmed when the operation is going to fail anyway, and doing so might allow the client to game things such that it wouldn't need to confirm a subsequent open with the same owner.
