As a side effect of the last patch of the series, introduced in v4, when 
subtest names on IGT side don't match test suite names on the kernel side we 
are now apparently getting completely empty KTAP reports from the kernel when 
using a filter_glob string that doesn't match any test suite name.  As a 
result, the tests are waiting for the KTAP report to appear in dmesg 
indefinitely, until interrupted by igt_runner on timeout.

If you think those timeouts provide a good reason for dropping that last patch 
from the series (I don't) then please speak up.

Thanks,
Janusz
