Hi, this is your Linux kernel regression tracker.

I noticed a regression report in bugzilla:

That's a commit the second patch from this series reverts. To my
untrained eyes it thus looks a lot like these change will resolve the
reported issue, which made me wonder:

* these patches afaics are not yet in mainline, is the plan to still
send it this cycle?

* there are no "CC: <stable..." tags in these patches. Is the plan to
manually ask for a backport? Or how can we get the regression fixed in
older releases?

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
