My test box is still on the same sha from this morning, which is:

commit 2ae08b36c06ea8df73a79f6b80ff7964e006e9e3 (origin/master, origin/HEAD)
Merge: 21f9c8a13bb2 8bb5e7f4dcd9
Author: Linus Torvalds <[email protected]>
Date:   Thu Aug 11 09:23:08 2022 -0700

    Merge tag 'input-for-v5.20-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

with io_uring-6.0 (ff34d8d06a1f16b6a58fb41bfbaa475cc6c02497) and
block-6.0 (aa0c680c3aa96a5f9f160d90dd95402ad578e2b0) pulled in, and it
builds just fine for me:
