From 79cc55422ce99be5964bde208ba8557174720893 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 31 Oct 2019 18:40:33 -0400 Subject: NFS: Fix an RCU lock leak in nfs4_refresh_delegation_stateid() A typo in nfs4_refresh_delegation_stateid() means we're leaking an RCU lock, and always returning a value of 'false'. As the function description states, we were always supposed to return 'true' if a matching delegation was found. Fixes: 12f275cdd163 ("NFSv4: Retry CLOSE and DELEGRETURN on NFS4ERR_OLD_STATEID.")
