Merge tag 'for-6.9/io_uring-20240310' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe: - Make running of task_work internal loops more fair, and unify how the different methods deal with them (me) - Support for per-ring NAPI. The two minor networking patches are in a shared branch with netdev (Stefan) - Add support for truncate (Tony) - Export SQPOLL utilization stats (Xiaobing) - Multishot fixes (Pavel) - Fix for a race in manipulating the request flags via poll (Pavel) - Cleanup the multishot checking by making it generic, moving it out of opcode handlers (Pavel) - Various tweaks and cleanups (me, Kunwu, Alexander) * tag 'for-6.9/io_uring-20240310' of git://git.kernel.dk/linux: (53 commits) io_uring: Fix sqpoll utilization check racing with dying sqpoll io_uring/net: dedup io_recv_finish req completion io_uring: refactor DEFER_TASKRUN multishot checks io_uring: fix mshot io-wq checks io_uring/net: add io_req_msg_cleanup() helper io_uring/net: simplify msghd->msg_inq checking io_uring/kbuf: rename REQ_F_PARTIAL_IO to REQ_F_BL_NO_RECYCLE io_uring/net: remove dependency on REQ_F_PARTIAL_IO for sr->done_io io_uring/net: correctly handle multishot recvmsg retry setup io_uring/net: clear REQ_F_BL_EMPTY in the multishot retry handler io_uring: fix io_queue_proc modifying req->flags io_uring: fix mshot read defer taskrun cqe posting io_uring/net: fix overflow check in io_recvmsg_mshot_prep() io_uring/net: correct the type of variable io_uring/sqpoll: statistics of the true utilization of sq threads io_uring/net: move recv/recvmsg flags out of retry loop io_uring/kbuf: flag request if buffer pool is empty after buffer pick io_uring/net: improve the usercopy for sendmsg/recvmsg io_uring/net: move receive multishot out of the generic msghdr path io_uring/net: unify how recvmsg and sendmsg copy in the msghdr ...
