I'm building an io loop around io uring and the app waits for pending completions using `io_uring_submit_and_wait_timeout` but sometimes I want to just interrupt the wait or submit another operations...
One possible use for io_uring might be to process data in a file with the following loop: for (;;) { reap_io_completions(); submit_new_io_requests(); process_completions(); // this takes a bit of time...
Let me preface this by saying that this is most certainly a *me* problem (also I am on Linux 5.15) ### Background Because reasons, I need to use `io_uring` directly...

When a ring is set up with IORING_SETUP_DEFER_TASKRUN, and I then submit 100 read requests and sleep a second for all of them to complete, calling io_uring_wait_cqes() with wait_nr =...
Our applications writes to a file (XFS), and uses the `IOSQE_ASYNC` flag. The application can submit up to 8 operations at any point of time. Once 8 operations are in-flight,...
hello, I wrote 1Gbytes to a slow u-disk, wait for all write request completed, and then submit close, the io_uring_wait_cqe will be blocked a long time(io_uring_wait_cqe will not return intime),...
I made message broadcasting server using napi-busy-poll-server examples. And I want to process batch completion to consume CQ faster. So, I need to submit multiple receivePings for that. In this...
As the title says, combining recvmsg_multishot with IOU_PBUF_RING_INC causes spurious BADADDR errors. Is this an unsupported combo or just an edge case that I've discovered? My use case is that...
