Merge tag 'for-5.20/io_uring-2022-07-29' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe: - As per (valid) complaint in the last merge window, fs/io_uring.c has grown quite large these days. io_uring isn't really tied to fs either, as it supports a wide variety of functionality outside of that. Move the code to io_uring/ and split it into files that either implement a specific request type, and split some code into helpers as well. The code is organized a lot better like this, and io_uring.c is now < 4K LOC (me). - Deprecate the epoll_ctl opcode. It'll still work, just trigger a warning once if used. If we don't get any complaints on this, and I don't expect any, then we can fully remove it in a future release (me). - Improve the cancel hash locking (Hao) - kbuf cleanups (Hao) - Efficiency improvements to the task_work handling (Dylan, Pavel) - Provided buffer improvements (Dylan) - Add support for recv/recvmsg multishot support. This is similar to the accept (or poll) support for have for multishot, where a single SQE can trigger everytime data is received. For applications that expect to do more than a few receives on an instantiated socket, this greatly improves efficiency (Dylan). - Efficiency improvements for poll handling (Pavel) - Poll cancelation improvements (Pavel) - Allow specifiying a range for direct descriptor allocations (Pavel) - Cleanup the cqe32 handling (Pavel) - Move io_uring types to greatly cleanup the tracing (Pavel) - Tons of great code cleanups and improvements (Pavel) - Add a way to do sync cancelations rather than through the sqe -> cqe interface, as that's a lot easier to use for some use cases (me). - Add support to IORING_OP_MSG_RING for sending direct descriptors to a different ring. This avoids the usually problematic SCM case, as we disallow those. (me) - Make the per-command alloc cache we use for apoll generic, place limits on it, and use it for netmsg as well (me). - Various cleanups (me, Michal, Gustavo, Uros) * tag 'for-5.20/io_uring-2022-07-29' of git://git.kernel.dk/linux-block: (172 commits) io_uring: ensure REQ_F_ISREG is set async offload net: fix compat pointer in get_compat_msghdr() io_uring: Don't require reinitable percpu_ref io_uring: fix types in io_recvmsg_multishot_overflow io_uring: Use atomic_long_try_cmpxchg in __io_account_mem io_uring: support multishot in recvmsg net: copy from user before calling __get_compat_msghdr net: copy from user before calling __copy_msghdr io_uring: support 0 length iov in buffer select in compat io_uring: fix multishot ending when not polled io_uring: add netmsg cache io_uring: impose max limit on apoll cache io_uring: add abstraction around apoll cache io_uring: move apoll cache to poll.c io_uring: consolidate hash_locked io-wq handling io_uring: clear REQ_F_HASH_LOCKED on hash removal io_uring: don't race double poll setting REQ_F_ASYNC_DATA io_uring: don't miss setting REQ_F_DOUBLE_POLL io_uring: disable multishot recvmsg io_uring: only trace one of complete or overflow ...
