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!
