This one was cc'ed to stable@...r.kernel.org.  But when you said "I
notice, that neither of thse have made it into 2.6.5", I assume you
meant 3.5?  The last 3.5 kernel is 3.5.7, and Greg K-H isn't
backporting fixes to 3.5.x any more.  (See http://www.kernel.org to
see which kernels are marked "EOL"; those are the ones which are no
longer getting updates.)

So that means it should eventually make it to the 3.4.x and 3.6.x
kernels.

I missed this one because the subject line didn't have [PATCH] in it.
(Darrick, it really helps if you use git format-patch / git
send-email; you can use a message-id of the message you're replying to
in the mail thread to chain the message to the thread.)

I would have eventually found it in patchwork, but even in patchwork
the listing would have had a potentially misleading subject line,
since it grabs the patch title from the subject line of the e-mail.

It isn't in 3.7-rc3 because I didn't see it before I sent the pull
request to Linus....

At this point I'll just include it in the patches to be sent to Linus
at the next merge window, mainly because I don't have the time to run
a separate regression test run just for this patch, and it's only a
cosmetic issue, right?
