From ed4a3983cd3eb93aaf80de8d8a36efed808acff2 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Thu, 15 Aug 2019 15:32:17 +0100 Subject: [PATCH] tools: bpftool: fix argument for p_err() in BTF do_dump() The last argument passed to one call to the p_err() function is not correct, it should be "*argv" instead of "**argv". This may lead to a segmentation fault error if BTF id cannot be parsed correctly. Let's fix this.
