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. |
|
