Summary
ref_tracker: implement use-after-free detection
Details

In the Linux kernel, the following vulnerability has been resolved:

ref_tracker: implement use-after-free detection

Whenever reftrackerdirinit() is called, mark the struct reftracker_dir as dead.

Test the dead status from reftrackeralloc() and reftrackerfree()

This should detect buggy devput()/devhold() happening too late in netdevice dismantle process.
