Hi, Thorsten here, the Linux kernel's regression tracker.

Miri, I noticed a report about a regression in bugzilla.kernel.org for
some code you maintain. As many (most?) kernel developers don't keep an
eye on the bug tracker, I decided to write this mail. To quote from
https://bugzilla.kernel.org/show_bug.cgi?id=218946 :

The reporter later confirmed that 6.9 is working fine.

See the ticket for more details. Note, you have to use bugzilla to reach
the reporter, as I sadly[1] can not CCed them in mails like this.

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

Everything you wanna know about Linux kernel regression tracking:
https://linux-regtracking.leemhuis.info/about/#tldr
If I did something stupid, please tell me, as explained on that page.

[1] because bugzilla.kernel.org tells users upon registration their
"email address will never be displayed to logged out users"

P.S.: let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:
