Subject: NFSv4.1: Ensure state manager thread dies on last umount
From: Trond Myklebust <[email protected]>
commit 47c2199b6eb5fbe38ddb844db7cdbd914d304f9c upstream.
Currently, the state manager may continue to try recovering state forever
even after the last filesystem to reference that nfs_client has umounted.
