From: Mircea Cirjaliu <mcirja...@bitdefender.com> commit 301a33d51880619d0c5a581b5a48d3a5248fa84b upstream.
I assume this was obtained by copy/paste. Point it to bpf_map_peek_elem() instead of bpf_map_pop_elem(). In practice it may have been less likely hit when under JIT given shielded via 84430d4232c3 ("bpf, verifier: avoid retpoline for map push/pop/peek operation").
