====================
eBPF-based device cgroup controller
This patchset introduces an eBPF-based device controller for cgroup v2.
Patches (1) and (2) are a preparational work required to share some code
with the existing device controller implementation.
Patch (3) is the main patch, which introduces a new bpf prog type
and all necessary infrastructure.
Patch (4) moves cgroup_helpers.c/h to use them by patch (4).
Patch (5) implements an example of eBPF program which controls access
to device files and corresponding userspace test.
