Thanks Marc, do you have any broader comments on the implications of iouring for libev? It looks like iouring is finally bringing async system calls (not just async io) to Linux. Will libeio have an iouring backend that doesn't use a thread pool and instead hands the io off to the kernel with io_uring?
In the Mesos project we have been using libev for some time, but in oder to get the benefits of iouring we'd want to be handing off the work to the kernel via iouring and not use io threads. Will libeio be providing this?
