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
