From 5b180973d90475ab32c470e568f1c786d94a9bf0 Mon Sep 17 00:00:00 2001 From: John Kacur Date: Thu, 29 Nov 2018 15:39:22 +0100 Subject: [PATCH] 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 make sure the max_comm_len defaults to 0 instead of generating an error.
