Linux 5.12-rc2

[Linus Torvalds <torvalds@linux-foundation.org>]

Ok, so this is a couple of days early, but rc1 had the nasty swapfile
issue, so I'm just accelerating rc2 a bit.

Outside of the swapfile IO offset fix, the only other thing that
stands out is some io_uring thread handling re-organization, which not
only solved a few fundamental issues, but actually made the code
smaller and simpler too.

Other than that it all looks pretty normal: drivers dominate (with
sound being most notable, with the ASoC Intel SOF support being split
up sanely). But there's some btrfs work, kvm, iscsi, etc. A few random
things all over.

Shortlog appended for your viewing pleasure, and I sincerely hope (and
believe) that rc2 is in a lot better shape than rc1 was.
