A change of maintainership for linux-next

Stephen Rothwell, who has maintained the kernel's linux-next integration
tree from its inception, has announced his
retirement from that role:

I will be stepping down as Linux-Next maintainer on Jan 16, 2026.
Mark Brown has generously volunteered to take up the challenge. He
has helped in the past filling in when I have been unavailable, so
hopefully knows what he is getting in to. I hope you will all
treat him with the same (or better) level of respect that I have
received.

It has been a long but mostly interesting task and I hope it has
been helpful to others. It seems a long time since I read Andrew
Morton's 'I have a dream' email and decided that I could help out
there - little did I know what I was heading for.

Over the last two decades or so, the kernel's development process has evolved
from an unorganized mess with irregular releases to a smooth machine with a
new release every nine or ten weeks. That would not have happened without
linux-next; thanks are due to Stephen for helping to make the current
process possible.
