[ 12/38] NFSv4: nfs4_locku_done must release the sequence id

From: Greg Kroah-Hartman
Date: Wed Nov 14 2012 - 23:48:46 EST


3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx>

commit 2b1bc308f492589f7d49012ed24561534ea2be8c upstream.

If the state recovery machinery is triggered by the call to
nfs4_async_handle_error() then we can deadlock.
