Hmm. Not an upstream commit ID, so this is presumably a backport.
Ok, let's see what it is using the web link:

Yeah, that just gives a github 404 error.
I'm _assuming_ it's the WARN_ON_IN_IRQ() in the access_ok().
Which doesn't much make sense either (why wouldn't it happen in
mainline)? But without a useful web link to see what is actually being
tested, I guess it's not something I can even look at...
