"negated to the down_trylock() return values" probably means !down_trylock
which is already obvious. So what does the comment mean?
the comment comes to warn people that a code that was using
if(!down_trylock(foo)) need to be changed to if(mutex_trylock(foo)) and
viseversa (code that was using if(down_trylock(foo)) etc) - that's all.
