This is shamelessly stolen from the mm side. Even though referencing is mostly single/dual user, the 128 count was retained to keep the code the same. Maybe this should/could be made generic at some point. - Removal of the need to have a manager thread for each ring. The manager threads only job was checking and creating new io-threads as needed, instead we handle this from the queue path. - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this thread is "just" a regular application thread, so no need to restrict use of it anymore. - Cleanup of how internal async poll data lifetime is managed. - Fix for syzbot reported crash on SQPOLL cancelation. - Make buffer registration more like file registrations, which includes flexibility in avoiding full set unregistration and re-registration. - Fix for io-wq affinity setting. - Be a bit more defensive in task->pf_io_worker setup. - Various SQPOLL fixes. - Cleanup of SQPOLL creds handling. - Improvements to in-flight request tracking. - File registration cleanups. - Tons of cleanups and little fixes * tag 'for-5.13/io_uring-2021-04-27' of git://git.kernel.dk/linux-block: (156 commits) io_uring: maintain drain logic for multishot poll requests io_uring: Check current->io_uring in io_uring_cancel_sqpoll io_uring: fix NULL reg-buffer io_uring: simplify SQPOLL cancellations io_uring: fix work_exit sqpoll cancellations io_uring: Fix uninitialized variable up.resv io_uring: fix invalid error check after malloc io_uring: io_sq_thread() no longer needs to reset current->pf_io_worker kernel: always initialize task->pf_io_worker to NULL io_uring: update sq_thread_idle after ctx deleted io_uring: add full-fledged dynamic buffers support io_uring: implement fixed buffers registration similar to fixed files io_uring: prepare fixed rw for dynanic buffers io_uring: keep table of pointers to ubufs io_uring: add generic rsrc update with tags io_uring: add IORING_REGISTER_RSRC io_uring: enumerate dynamic resources io_uring: add generic path for rsrc update io_uring: preparation for rsrc tagging io_uring: decouple CQE filling from requests ... |
