I think what Mark is trying to say is to include a fuller description of
the problem, and don't expect people to fire up their web browser to get
a basic overview of what the problem is.

My guess is that the problem _appears_ to be that someone's added a call
to debug_check_no_locks_held() into schedule_hrtimeout_range_clock()
without considering what this means.

What it means is that you can't now use usleep_range() from within any
driver probe function - which is absolutely absurd.
