Use timeouts?
- geofft 6y agoHow exactly? I/O in TASK_UNINTERRUPTIBLE/TASK_KILLABLE cannot be timed out - so part of my question is how io_uring handles that in general.
- cyphar 6y agoIf it's just blocked, you could probably look at the io_uring kthreads. But as I mentioned in another comment, bpftrace is probably a more useful tool for things like this (and it's useful for general kernel debugging too!).
