Should we somehow coordinate so that our > branches don't conflict? Any suggestions? A conflict can't be avoided, but if you pick system call number 427 for pidfd_send_signal, and Jens picks numbers 424 through 426 for io_uring on all architectures, we can hopefully avoid the renumbering. Of course, if one or more of the patch series don't make it in or see a rework that changes the number of new syscalls, then we may have to change the numbers after all, but we can always hope ;-) Arnd
