-When CONFIG_BPF_JIT_ALWAYS_ON is enabled, bpf_jit_enable is permanently set to 1 and
-setting any other value than that will return in failure. This is even the case for

-is discouraged and introspection through bpftool (under tools/bpf/bpftool/) is the
-generally recommended approach instead.
-
-In the kernel source tree under tools/bpf/, there's bpf_jit_disasm for
-generating disassembly out of the kernel log's hexdump::
