Nack.
I really don't like it.

There were days in the past when the kernel generating bpf directly was appealing.
These days are gone. Performance improvements for fetchargs is not a good reason

Why is performance *not* a good reason?

to add all this complexity and bypass verifier checks.

The code lives in the kernel. What reason is there to add verification
checks? The point of verification is because we don't trust user space. Why
do we not trust the kernel?

bpf insns should come from user space.

Why?

because I see this patchset as pointless kernel bloat with the "help" of bpf.
Hence the nack to avoid dragging bpf into this.

Call it philosophical disagreement if you like.
