I don't see the big issue. There is no other way in Linux or Posix to open a file asynchronously (not sure about closing). Dan Bernstein complained about that 20 years ago(?) and io_uring finally fixes it. Before that, runtimes with lightweight processes/threads (Erlang, GHC) used a Posix threadpool to open files in the background. That seems just as messy as using io_uring, which at least keeps everything in the same thread. http://cr.yp.to/unix/asyncdisk.html |
