Hello Boris,

I am grateful that you took the time to respond and say it will be fixed soon.
By soon, I presume that means within two weeks as the guidance for
fixing regressions recommends:

https://www.kernel.org/doc/html/latest/process/handling-regressions.html

Quoting from that page: "Try to fix regressions quickly once the culprit has
been identified; fixes for most regressions should be merged within two
weeks, but some need to be resolved within two or three days."

If the regression is not fixed by the end of August, I don't think it would
be "nonsense" for me to send another PING at that time. I also think the
PING I sent earlier today is not "nonsense," given that this regression has been
waiting for a fix for over three months, which is much longer than the
expected time to fix a regression of two weeks.

Best regards,

Chuck
