bpf: Introduce sysctl kernel.bpf_force_dyn_alloc. Introduce sysctl kernel.bpf_force_dyn_alloc to force dynamic allocation in bpf hash map. All selftests/bpf should pass with bpf_force_dyn_alloc 0 or 1 and all bpf programs (both sleepable and not) should not see any functional difference. The sysctl's observable behavior should only be improved memory usage. Acked-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
