No. (Not for security reasons, but for lack of an army of motivated and talented developers like Jens Axboe et al.)

Right. kqueue is more like an extended version of epoll.
- hedora 3y agoWell, it does, in that most modern hardware devices communicate over PCIe via SQ/CQ pairs, and I'm pretty sure that include virtualization device interfaces. A lot of people are coming to the conclusion that io_uring's userspace interface is fundamentally insecure. That couldn't be farther from the truth. I've read the spec (which is only a few pages). I could implement + security validate both sides in a day or two (and have done similar in the past).
