| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <Trond.Myklebust@netapp.com>
commit e59d27e05a6435f8c04d5ad843f37fa795f2eaaa upstream.
Firstly, task->tk_status will always return negative error values, so the current tests for 'NFS4ERR_DELEG_REVOKED' etc. are all being ignored. Secondly, clean up the code so that we only need to test task->tk_status once!
