I don't know about bpf and kprobes, but for ftrace, the only place that
it allocates text happens to be in arch specific code.
If you want something special for ftrace, you could just add your own
function. But for x86, a text_alloc_immediate() would work.
(BTW, I like the function names over the enums)
