Description

Untracking a user space pid which is not tracked results in an invalid parameter error which is inconsistent with the output provided when the same action is performed on the kernel domain.

Userspace:

$ lttng create test
Session test created.
Traces will be written in /home/jgalar/lttng-traces/test-20150904-172530
$ lttng untrack -u -p 555
Error: Invalid parameter
Error: Command error

Kernel:

$ lttng create test
Session test created.
Traces will be written in /home/jgalar/lttng-traces/test-20150904-173144

$ lttng untrack -k -p 555
Warning: PID 555 not tracked in session test
