[PATCH 0/2] bpf: classify block device hooks and add selftests

[Christian Brauner <brauner@kernel.org>]

A bunch of new hooks for managing block devices were added a while ago
but they weren't appropriately classified. Classify them and add a test
program so we catch regressions.

Note that for whatever reason building the bpf selftests locally seems
to fail for all kinds of arcane reasons for me. That might just be my
fault. I added a pr against the ci to have the selftests run but to test
this meaningfully it needs veritysetup and dmverity support. I'm not
sure if that's available already.
