Huh, a -rc on Saturday evening? That's unusual. But well, in that case I
can wait till tomorrow with my regression report, as it's too late for
the rc anyway. :-D

But nevertheless there is one thing I want to bring up, even if -rc5 is
already out: Vlastimil asked me explicitly to highlight ```Revert
"mm/compaction: fix set skip in fast_find_migrateblock"```[1] in my
weekly report[2], as me would prefer if that patch could head to
mainline and especially stable rather sooner than later. He wrote:

```I consider this serious enough to be fixed in mainline+stable ASAP,
hopefully in rc5, as it does hurt people using 6.1.```

See [3] and [4] for the regression reports.

Andrew merged that patch on the 13th[5]. The fix thus by now spend a few
days in linux-next. But that hasn't been the the case yet when Andrew
sent the latest -mm hotfixes to you on the 16th, that's why it's still
in mm.

It's too late now to get it included in -rc5, but maybe Greg is willing
to pick it up for the next stable cycle if you merge it to mainline
today. But obviously it's your decision if that's worth it. And yes,
ideally I should have asked Andrew to send a extra pull request your
way, but I was busy with other stuff and only saw Vlastimil a few hours
ago. :-/ Sorry.

Ciao, Thorsten
