Thanks!

I just don't think there are many real users of linux-next. The code
leading to the 5.19 revert sat in linux-next for a long time and no one
noticed anything. It wasn't until the 5.19-rc's started coming out that
real testing (and bug reporting) occurred.
I think linux-next is great for the kernel robots to work their magic,
but I don't know if having something in linux-next for 6 weeks is any
better than only 2 weeks.
