CHANGES: New features: - Add `Eio.Path.symlink` (@patricoferris ocaml-multicore/eio#715, reviewed by @talex5). - Add `Eio.Pool.use ~never_block` (@SGrondin ocaml-multicore/eio#657, reviewed by @talex5). - Add `Eio_unix.Net.import_socket_listening` (@alyssais ocaml-multicore/eio#733). - Add `Eio.Time.Timeout.sleep` (@talex5 ocaml-multicore/eio#726). Documentation: - Add `examples/fs` showing how to walk a directory tree (@talex5 ocaml-multicore/eio#730). - README: explain that `read_all` reads until shutdown (@talex5 ocaml-multicore/eio#717, reported by @Wenke-D). - Use long dash in README title (@lucperkins ocaml-multicore/eio#718). Linux backend: - Require Linux >= 5.15 (@talex5 ocaml-multicore/eio#720, reviewed by @SGrondin and @avsm). Removes a work-around that required checking whether every flow was a tty. - Don't call submit immediately before wait (@talex5 ocaml-multicore/eio#728). This is slightly faster and makes the traces clearer. - Don't record submit events when there's nothing to submit (@talex5 ocaml-multicore/eio#729). Makes the traces a bit clearer. - Split flow into its own file (@talex5 ocaml-multicore/eio#727). - Add work-around for signals race (@talex5 ocaml-multicore/eio#734). POSIX backend: - Add `_BSD_SOURCE` flag to fix build on OpenBSD (@prgbln ocaml-multicore/eio#722). - Fix sandboxed path resolution on OpenBSD (@jebrosen ocaml-multicore/eio#723, reviewed by @talex5). OpenBSD uses `ELOOP` when opening a symlink with `O_NOFOLLOW`. Build and test: - Benchmarks: record uname, Eio backend, and number of cores (@talex5 ocaml-multicore/eio#719). - Update to MDX 2.4.1 for OCaml 5.2 (@talex5 ocaml-multicore/eio#712).

It reported that the domain was suspended during all calls to
submit, but in fact uring doesn't make a syscall if there's nothing to submit. This leads to short bogus suspend regions on traces, which are distracting. e.g. tracingexamples/netshows this bogus 100ns suspend:
