Hi, I am playing with io_uring interface and for some reason it is causing freezing my pc. Here is some example code which cause this: https://bitbucket.org/kozzi11/uring_hang/src/master/main.c When runing this and test it with wrk (https://github.com/wg/wrk) : wrk --latency -d 15 -c 2048 --timeout 8 -t 8 http://localhost:8080/ it completly hang pc. Thank you for any hint if there is something wrong with way how I am using io_uring interface or it is a bug in io_uring itself. Daniel Kozak
