If it was just in the normal development release in an RC I'd agree there wasn't
a lot of urgency, but stable picked it up and caused severe regressions.  There
wasn't an obvious willingness to revert the problematic commit in stable is why
Thorsten was making noise about it and suggested me to send it directly to Linus.

Anyway - I'm glad it's sorted now.
