Ok, seems I didn't understand this process correctly. I reposted the
new "fixed" version of this patch, because I thought it is more
suitable for stale to merge one correct patch rather than one
incorrect + follow-on fixup. Sorry if I was wrong.

Steve has just merged the follow-on patch:
http://git.samba.org/?p=sfrench/cifs-2.6.git;a=commit;h=ce85852b90a214cf577fc1b4f49d99fd7e98784a

but seems hasn't sent a merge request to Linus yet - will let you know
when the patch comes to Linus's tree.
