When applying the fix I went with:

Diagnosed-by: Linus Torvalds <torvalds@linux-foundation.org>

Because I think 'diagnosing' a bug is a higher category, which implies debugging.

( Sometimes we refer to 'debugging a bug' as the reporter adding printks on
request and printing out key state that helps understand the bug. It does not
necessarily imply root-causing the bug. )

Also note that I added a "Reported-and-Bisected-by:" tag for the ktest robot, to
further credit the fact that in addition to reporting a kernel crash, a specific
commit was bisected to as well.

I'll wait for another round of ktest robot testing to make sure the crash is
indeed fixed.

Thanks,

Ingo
