From 01126c4488c6869e2c2527df28189aa28f21de5b Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Mon, 2 Dec 2019 21:06:40 +0800 Subject: [PATCH] tools: bpftool: fix completion for "bpftool map update" [ Upstream commit fe8ecccc10b3adc071de05ca7af728ca1a4ac9aa ] When trying to complete "bpftool map update" commands, the call to printf would print an error message that would show on the command line if no map is found to complete the command line. Fix it by making sure we have map ids to complete the line with, before we try to print something.
