The issue is related to the io uring feature in the Linux kernel, where the function `io uring cancel sqpoll()` is intended to cancel all requests of a specified context. However, it uses per-task counters to track the number of inflight requests, which can lead to the function going to sleep waiting for requests to appear that will never happen. This can cause the task to hang. The issue affects contexts that share sqpoll and continue to use shared counters.
