Cover letter [PATCH 0/3] relay buffer-only channels (resubmit)
Hello,
This is a resubmit of the buffer-only channels implementation for relay. Basically I followed Pekka Enberg's suggestion of doing things CPU-hotplug-aware.
The first two patches allow relay to set up an early initcall for registering a CPU hotplug notifier. This has to run before SMP is up, so non-boot CPUs get a buffer as soon as they're up.
Feel free to ask any questions or suggest anything.
