Vasily Averin 84779085fa lockd: lost rollback of set_grace_period() in lockd_down_net() ... commit 3a2b19d1ee5633f76ae8a88da7bc039a5d1732aa upstream. Commit efda760fe9 ("lockd: fix lockd shutdown race") is incorrect, it removes lockd_manager and disarm grace_period_end for init_net only. If nfsd was started from another net namespace lockd_up_net() calls set_grace_period() that adds lockd_manager into per-netns list and queues grace_period_end delayed work. These action should be reverted in lockd_down_net(). Otherwise it can lead to double list_add on after restart nfsd in netns, and to use-after-free if non-disarmed delayed work will be executed after netns destroy.
