I plan on sending the pidfd branch with the new pidfd_send_signal()
syscall for the 5.1 window. 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 ;-)
