Sorry that I didn't follow up on this but I recently changed jobs and
was quite busy and travelling.

The problem as is explained above in the quoted text is that $subject
is not enough to fix the issue, patch 1/3 should also be picked but
that is waiting for Olof's ack.
I agree that both patches 1/3 and 2/3 have to be sent as an -rc fix
since the commit that introduced the issue made it to 4.2.

Patch 3/3 can wait for 4.3 which BTW I see that has not been applied either.
