This contains fixes to the stuff that already went in, cleanups, and a few later additions. In particular, this contains: - Cleanups/fixes/unification of the submission and completion path (Pavel,me) - Linked timeouts improvements (Pavel,me) - Error path fixes (me) - Fix lookup window where cancellations wouldn't work (me) - Improve DRAIN support (Pavel) - Fix backlog flushing -EBUSY on submit (me) - Add support for connect(2) (me) - Fix for non-iter based fixed IO (Pavel) - creds inheritance for async workers (me) - Disable cmsg/ancillary data for sendmsg/recvmsg (me) - Shrink io_kiocb to 3 cachelines (me) - NUMA fix for io-wq (Jann)" * tag 'for-5.5/io_uring-post-20191128' of git://git.kernel.dk/linux-block: (42 commits) io_uring: make poll->wait dynamically allocated io-wq: shrink io_wq_work a bit io-wq: fix handling of NUMA node IDs io_uring: use kzalloc instead of kcalloc for single-element allocations io_uring: cleanup io_import_fixed() io_uring: inline struct sqe_submit io_uring: store timeout's sqe->off in proper place net: disallow ancillary data for __sys_{send,recv}msg_file() net: separate out the msghdr copy from ___sys_{send,recv}msg() io_uring: remove superfluous check for sqe->off in io_accept() io_uring: async workers should inherit the user creds io-wq: have io_wq_create() take a 'data' argument io_uring: fix dead-hung for non-iter fixed rw io_uring: add support for IORING_OP_CONNECT net: add __sys_connect_file() helper io_uring: only return -EBUSY for submit on non-flushed backlog io_uring: only !null ptr to io_issue_sqe() io_uring: simplify io_req_link_next() io_uring: pass only !null to io_req_find_next() io_uring: remove io_free_req_find_next() ...
