bpf: drop bpf_verifier_lock Drop bpf_verifier_lock for root to avoid being DoS-ed by unprivileged. The BPF verifier is now fully parallel. All unpriv users are still serialized by bpf_verifier_lock to avoid exhausting kernel memory by running N parallel verifications. Signed-off-by: Alexei Starovoitov <ast@kernel.org>
