LTTng

test_valid_filter as a few failing test cases:

test_valid_filter (Wstat: 2048 Tests: 662 Failed: 8)
  Failed tests:  553, 559, 565, 571, 577, 583, 589, 595
  Non-zero exit status: 8

All failures are triggered by the 'Validate trace filter output' step of their respective test case.

I witnessed this problem on master of both lttng-modules and lttng-tools.

Here is the output of the failing tests:
