Eric Dumazet 914a7b5000 lib: add tests for reference tracker 
This module uses reference tracker, forcing two issues.

1) Double free of a tracker

2) leak of two trackers, one being allocated from softirq context.

"modprobe test_ref_tracker" would emit the following traces.
(Use scripts/decode_stacktrace.sh if necessary)
