Merge tag 'io_uring-6.17-20250808' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
- Allow vectorized payloads for send/send-zc - like sendmsg, but
without the hassle of a msghdr.
- Fix for an integer wrap that should go to stable, spotted by syzbot.
Nothing alarming here, as you need to be root to hit this.
Nevertheless, it should get fixed.
FWIW, kudos to the syzbot crew for having much nicer reproducers now,
and with nicely annotated source code as well. This is particularly
useful as syzbot uses the raw interface rather than liburing,
historically it's been difficult to turn a syzbot reproducer into a
meaningful test case. With the recent changes, not true anymore!
