4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakub Kicinski <jakub.kicinski@xxxxxxxxxxxxx>
[ Upstream commit ab7f5bf0928be2f148d000a6eaa6c0a36e74750e ]
Comments in the verifier refer to free_bpf_prog_info() which
seems to have never existed in tree. Replace it with
free_used_maps().
