Sorry for taking so long to get to this one here.

Is the Mesa MR really ready to get merged right after we merge this kernel series?
Are all of the patches there really reviewed? I couldn't make a sense of the open
MR discussions and I noticed the MR is still marked as 'Draft:'.

But once we are sure that Mesa is ready and all Michal's concerns on the latest
version of the kernel series are solved, then we can definitely merge.

Deadline for 6.11 is Wednesday next week(Jun/26).

Thanks,
Rodrigo.
