Hi all, this series changes the sysctl ->proc_handler methods to take kernel pointers. This simplifies some of the pointer handling in the methods (which could probably be further simplified now), and gets rid of the set_fs address space overrides used by bpf. Changes since v2: - free the buffer modified by BPF - move pid_max and friends to pid.h Changes since v1: - drop a patch merged by Greg - don't copy data out on a write - fix buffer allocation in bpf
