Cover letter [PATCH net-next v2 0/5] BPF/random32 updates
BPF update to split the prandom state apart, and to move the *once helpers to the core. For details, please see individual patches. Given the changes and since it's in the tree for quite some time, net-next is a better choice in our opinion.
v1 -> v2:
- Make DO_ONCE() type-safe, remove the kvec helper. Credits go to Alexei Starovoitov for the __VA_ARGS__ hint, thanks!
- Add a comment to the DO_ONCE() helper as suggested by Alexei.
- Rework prandom_init_once() helper to the new API.
- Keep Alexei's Acked-by on the last patch.
Thanks!
