io_uring doesn't support getdents though. so the primary benefit is bulk statting (ls -l). It'd be nice if we could have a getdents in flight while processing the results of the previous one.

POSIX adopting NFS' "readdirplus" operation (getdents + stat) could negate some of the benefit towards io_uring, too.

Yeah. To be clear I don't think Linux or Posix will ever adopt readdirplus as an API.
