Subject: [PATCH 1/5] nfsd: don't try to shut down nfs4 state handling unless it's up
Date: Mon, 19 Jul 2010 16:50:04 -0400 [thread overview]
Message-ID: <1279572608-7234-2-git-send-email-jlayton@redhat.com> (raw)
In-Reply-To: <1279572608-7234-1-git-send-email-jlayton@redhat.com>
If someone tries to shut down the laundry_wq while it isn't up it'll
cause an oops.
