Merge tag 'io_uring-6.2-2023-01-20' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe: "Fixes for the MSG_RING opcode. Nothing really major: - Fix an overflow missing serialization around posting CQEs to the target ring (me) - Disable MSG_RING on a ring that isn't enabled yet. There's nothing really wrong with allowing it, but 1) it's somewhat odd as nobody can receive them yet, and 2) it means that using the right delivery mechanism might change. As nobody should be sending CQEs to a ring that isn't enabled yet, let's just disable it (Pavel) - Tweak to when we decide to post remotely or not for MSG_RING (Pavel)" * tag 'io_uring-6.2-2023-01-20' of git://git.kernel.dk/linux: io_uring/msg_ring: fix remote queue to disabled ring io_uring/msg_ring: fix flagging remote execution io_uring/msg_ring: fix missing lock on overflow for IOPOLL io_uring/msg_ring: move double lock/unlock helpers higher up
