Great, thx for the reply.

Shreeya, normally I believe developers in cases like this and would have
included

 #regzbot fix: f100ce3bbd6

in this mail (without the space in front of the #) to mark the
regression as resolved. Would that be okay for you and other kernel.ci
people? Or do you want to confirm this first?

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