Yeah, I pushed this too soon, fixed now.

But why are you even testing this branch? I didn't include dm-5.19 in
linux-next yet.

Hi Mike,

The bot picks up all branches to test, do you want it to only test few branches?



Given that it seems strange for the bot to just pick up some branch,
and then spam LKML, dm-devel, etc like it found a meaningful problem.

we also support sending reports privately, do you want this way?

Best Regards,
Rong Chen


Mike
