Polling an FD is so last century :) to be honest, I don't know anyone use netlink and why hope receive low memory notify by netlink. poll() is old way, but it works good enough. and, netlink have a bit weak point. end up, netlink philosophy is read/write model. I afraid to many low-mem message queued in netlink buffer at under heavy pressure. it cause degrade memory pressure. > Still, it is good to start with some code - eventually we might just > have a full reservation API created.
