From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit a974deee477af89411e0f80456bfb344ac433c98 upstream.
If we exit because the file access check failed, we currently
leak the struct nfs4_state. We need to attach it to the
open context before returning.
Fixes: 3efb9722475e ("NFSv4: Refactor _nfs4_open_and_get_state..")
