From 6686390bab6a0e049fa7040631aee08b35a55293 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 12 Aug 2013 16:52:47 +1000 Subject: [PATCH] NFS: remove incorrect "Lock reclaim failed!" warning. After reclaiming state that was lost, the NFS client tries to reclaim any locks, and then checks that each one has NFS_LOCK_INITIALIZED set (which means that the server has confirmed the lock). However if the client holds a delegation, nfs_reclaim_locks() simply aborts (or more accurately it called nfs_lock_reclaim() and that returns without doing anything). This is because when a delegation is held, the server doesn't need to know about locks. So if a delegation is held, NFS_LOCK_INITIALIZED is not expected, and its absence is certainly not an error. So don't print the warnings if NFS_DELGATED_STATE is set.
