Merge tag 'io_uring-6.0-2022-09-18' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
"Nothing really major here, but figured it'd be nicer to just get these
flushed out for -rc6 so that the 6.1 branch will have them as well.
That'll make our lives easier going forward in terms of development,
and avoid trivial conflicts in this area.
- Simple trace rename so that the returned opcode name is consistent
with the enum definition (Stefan)
- Send zc rsrc request vs notification lifetime fix (Pavel)"
* tag 'io_uring-6.0-2022-09-18' of git://git.kernel.dk/linux:
io_uring/opdef: rename SENDZC_NOTIF to SEND_ZC
io_uring/net: fix zc fixed buf lifetime
