Alexei Starovoitov 60b58afc96 bpf: fix net.core.bpf_jit_enable race ... global bpf_jit_enable variable is tested multiple times in JITs, blinding and verifier core. The malicious root can try to toggle it while loading the programs. This race condition was accounted for and there should be no issues, but it's safer to avoid this race condition.
