We have also been informed about another regression these two commits
are causing:

https://lore.kernel.org/lkml/ace19af4-7cae-babd-bac5-cd3505dcd874@I-love.SAKURA.ne.jp/ (local)

I suggest to drop these two patches from this queue, and give us a
week to shake out the regressions of the change, and once ready, we
can include the complete set of fixes to stable (probably in a week or
two).
