[GIT PULL] io_uring updates for 6.7-rc1

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Here's the first batch of io_uring updates for the 6.7 merge window.
This contains the core bits, of which there are not many, and adds
support for using WAITID through io_uring and hence not needing to block
on these kinds of events. Outside of that, tweaks to the legacy provided
buffer handling and some cleanups related to cancelations for uring_cmd
support.

Please pull!
