[PATCH bpf-next v1 0/2] Open up res_spin_lock for tracing programs, fix is_tracing_prog_type()

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

Patches in the set first open up res_spin_lock in all program types. The
second patch goes back to addressing the technical debt highlighted in [0].
While for programs affected by the second patch don't need res_spin_lock
to be opened up (since it was already allowed in those program types due
to the oversight in is_tracing_prog_type()), it is timely to do so now.
