[PATCH 3.18 52/85] bpf: fix references to free_bpf_prog_info() in comments

From: Greg Kroah-Hartman
Date: Tue Aug 07 2018 - 14:58:38 EST


3.18-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().
