Subject: [PATCH 0/3] random: wire up in-kernel virtual machine fork notifications

As discussed, here is the notifier for learning when a virtual machine
forks, as well as a first use case for it, which is unsurprisingly
WireGuard, since I happen to know that case rather well.

The first patch is a small cleanup discovered when working on the second
patch, which is adding the actual notifier. The third case then
trivially adds it to WireGuard.

Jason A. Donenfeld (3):
  random: replace custom notifier chain with standard one
  random: provide notifier for VM fork
  wireguard: device: clear keys on VM fork
