From 0d08c381362aca8ef20c7fe1fa4c1ce36728208b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 19 Nov 2013 16:34:14 -0500 Subject: [PATCH] NFSv4: Update list of irrecoverable errors on DELEGRETURN commit c97cf606e43b85a6cf158b810375dd77312024db upstream. If the DELEGRETURN errors out with something like NFS4ERR_BAD_STATEID then there is no recovery possible. Just quit without returning an error. Also, note that the client must not assume that the NFSv4 lease has been renewed when it sees an error on DELEGRETURN.
