Ok. Ben. Could you please point me the source code of the error
injection framework? :-)
I think you're not talking about userland utility "errinject".

It's minimal, it's just the stuff in lib/fault-inject which provides
a framework for exposing attributes for injecting errors along with the
tool in tools/testing/fault-injection, at least that's my understanding.

Or we can just add stuff under debugfs/powerpc, which is what I did
for wsp.

Cheers,
Ben.
