Please read section 13 of Documentation/process/submitting-patches.rst 
for what this tag means; specifically, it is definitely not "this guy 
read my patch".

FWIW, in my case the patches I give trivial coding style comments on 
tend to be the ones I'm specifically *not* in a position to review in a 
technical capacity - the reason I'm looking at them in the first place 
is out of interest to learn more about how the relevant subsystems work.
