Hi, To what extent, if any, was the FlexSC paper an influence on io_uring? FlexSC is described in a paper from 2010: https://www.usenix.org/legacy/events/osdi10/tech/full_papers/Soares.pdf FlexSC is a system for asynchronous system calls aimed at achieving high-performance by avoiding the cost of system calls, in particular the locality costs of executing kernel code and user code on the same core. Implementation-wise, it seems broadly similar to io_uring, in that system calls are submitted by writing to some location in memory, which is later picked up by a syscall-execution thread (ala IORING_SETUP_SQPOLL) which executes it and writes back the result. I'm just curious if there was any influence from FlexSC on io_uring. Thanks, Spencer Baugh
