From e153f5177e1ae4b7859454a2d3011d6f55710600 Mon Sep 17 00:00:00 2001 From: John Kacur Date: Mon, 3 Dec 2018 09:02:34 -0500 Subject: [PATCH 2/2] python-linux-procfs: pflags: Ignore non-existent pids or process names If the user enters a non-existent pid or process name, skip over it. Also, if the user enters nothing but a non-existent pid, then don't calculte max_comm_len since you can't take the max of an empty list.
