Can you confirm that v6.1.47 doesn't have this regression? Is it also
reproducible on latest mainline?
Thanks.

No.
And I can confirm, it is a regression.
Latest mainline I'd like to avoid at this system.

Thanks for the regression report. I'm adding it to regzbot (as stable-specific
regression for now):
#regzbot ^introduced: v6.1.47..v6.1.48

Sorry, but to have your regression fixed, you have to check the mainline
to see if it still persists or not. And it is also helpful to perform
bisection (see Documentation/admin-guide/bug-bisect.rst for how).
Thanks.
