Subject[PATCH bpf-next] bpf: Allow bpf_jit_enable = 2 with BPF_JIT_ALWAYS_ON config
Date
After enabled BPF_JIT_ALWAYS_ON config, bpf_jit_enable always equals to
1; it is impossible to set 'bpf_jit_enable = 2' and the kernel has no
chance to call bpf_jit_dump().

This patch relaxes bpf_jit_enable range to [1..2] when kernel config
BPF_JIT_ALWAYS_ON is enabled so can invoke jit dump.
