This series adds support to liburing for the IORING_SETUP_DEFER_TASKRUN flag. The second half of the series is a bit mixed and includes some documentation fixes, overflow cleanups and test cleanups. I sent these a couple of months ago and forgot about it, but now it does depend on the new API so it needs to be ordered. I can send it separately if you like. Patches: 1 copies the definition from the kernel include file 2 introduces new APIs required for this feature 3/4/5 add tests for IORING_SETUP_DEFER_TASKRUN 6/7/8 clean and update existing documentation to match upstream 9 exposes the overflow state to the application 10 uses this and tests overflow functionality 11 gives an explicit warning if there is a short read in file-verify Dylan Yudaken (11): Copy defer task run definition from kernel add io_uring_submit_and_get_events and io_uring_get_events add a t_probe_defer_taskrun helper function for tests update existing tests for defer taskrun add a defer-taskrun test fix documentation shortenings update io_uring_enter.2 docs for IORING_FEAT_NODROP add docs for overflow lost errors expose CQ ring overflow state overflow: add tests file-verify test: log if short read man/io_uring_enter.2 | 24 +++- man/io_uring_setup.2 | 11 +- man/io_uring_wait_cqe.3 | 2 +- man/io_uring_wait_cqe_nr.3 | 2 +- man/io_uring_wait_cqe_timeout.3 | 2 +- man/io_uring_wait_cqes.3 | 2 +- src/include/liburing.h | 11 ++ src/include/liburing/io_uring.h | 7 + src/queue.c | 28 ++-- test/Makefile | 1 + test/cq-overflow.c | 248 +++++++++++++++++++++++++++++++- test/defer-taskrun.c | 217 ++++++++++++++++++++++++++++ test/eventfd-disable.c | 32 ++++- test/file-verify.c | 4 + test/helpers.c | 12 ++ test/helpers.h | 2 + test/iopoll.c | 16 ++- test/multicqes_drain.c | 49 ++++++- test/poll-mshot-overflow.c | 39 ++++- test/recv-multishot.c | 32 +++-- test/rsrc_tags.c | 10 +- 21 files changed, 697 insertions(+), 54 deletions(-) create mode 100644 test/defer-taskrun.c base-commit: 15cc446cb8b0caa5c939423d31182eba66141539 -- 2.30.2
