Dmitry, Jiri's report afaics made you quickly apply a revert that since
round about mid December is in -next:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=master&id=3c44e2b6cde674797b76e76d3a903a63ce8a18bb

But it looks like it never made it to mainline (or am I missing
something here? it feels like I do... anyway, moving on.). Was that
intentional or did that simply fall through the cracks due to the
festive season?

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