Subject: pull-request: uml 6.15-rc1 [resend]
Hi Linus, again,
And of course only I can get it wrong and mess up the most
basic list address. Sorry. This is just resend with the
correct address for linux-kernel this time, for the archive.
So I'm filling in for Richard (CC'ed) since he's been busy
and I've been mostly working on getting things reviewed and
merged this cycle. Nothing super exciting, see the summary
in the tag below.
Please pull and let us know if there's any problem.
Thanks,
johannes
