Hi, this is your Linux kernel regression tracker.

Thx for forwarding that report. CCing Aman, who authored that commit
(ac5408991ea6 in mainline, but it was backported to many stable kernels,
too)

Aman, could you look at this? If there is no easy fix in sight I wonder
if it might be the best to revert this soonish, so that Greg can pick up
that revert to stable quickly afterwards.

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.

P.P.S.: I for now assume that it's a problem that also is present in
mainline and thus will track it as such.
