I’m no kernel hacker, but it seems like io_uring is almost being undersold despite the hype. “Async IO” seems like an understatement. It’s (to my meager knowledge) a general purpose syscall batching interface. There could even be more interesting use-cases (like IPC?) in the future.
The genius (and in hindsight almost obvious) idea behind io_uring seems too good to ignore, which makes me hopeful about cross-platform adoption in the long run. That would enable huge simplifications in language runtimes and low-level frameworks, lowering the barrier of entry to high performance IO across the board.
