One note; there is a (interim) syscall number collision with the new
getrandom(2) system call.  I'm sure Linus will be able to handle it,
and fix it up, but I just wanted to give a heads up that depending on
which pull request hits mainline first, the syscall number for either
the new seccomp(2) or getrandom(2) may end up changing.

I've been warning people not to try to use getrandom(2) or check
anything into LibreSSL, et. al., until the patch is finalized and in
Linus's tree, but if you have userspace users already using the
syscall assignments in this patch series, please let me know and I can
try to make adjustments on my side.

Cheers,
