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.
