so instead of fixing the issue they found of being able to introduce backdoors in to their code, they are going to rollback thousand + of other bug fixes.
That's more of a story than what the researchers have done...
What would you do, if you had a group of patch authors who you didn't trust the contributions of anymore, other than setting aside the time for someone trusted to audit all 390 commits they've had since 2014?
I don't think it's necessarily a bruised ego here - I think what upset him is that the paper was published a few months ago and yet, based on this patch, the author seems to still be attempting to submit deeply flawed patches to LKML, and complaining when people don't trust them to be innocent mistakes for some reason.
