[PATCH] knfsd: fix nfs4_open lock leak
I just noticed that my patch "don't create on open that fails due to ERR_GRACE" (recently commited as fb553c0f17444e090db951b96df4d2d71b4f4b6b) had an obvious problem that causes a deadlock on reboot recovery. Sending in this now since it seems like a clear 2.6.16 candidate.--b. We're returning with a lock held in some error cases. Signed-off-by: J.
