From a8bfd2bc29f3bf35c7b588b102662375b0184475 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Thu, 8 Nov 2018 11:52:26 +0000 Subject: tools: bpftool: fix plain output and doc for --bpffs option Edit the documentation of the -f|--bpffs option to make it explicit that it dumps paths of pinned programs when bpftool is used to list the programs only, so that users do not believe they will see the name of the newly pinned program with "bpftool prog pin" or "bpftool prog load". Also fix the plain output: do not add a blank line after each program block, in order to remain consistent with what bpftool does when the option is not passed.
