I'll add one thing to Richard's complaint: please stop sending new
coding style or cosmetic changes until the previous ones have been
accepted.

There's a reason I don't apply those patches right away even though
they are simple. Those patches have a low priority in my review list
and improvements or fixes usually get reviewed before them. The reason
I do that is:

1/ I want to reward contributors who submit things that actually matter
   to the subsystem
2/ It tends to discourage drive-by contributors whose only interest is
   to get a lot of trivial patches in the kernel

Note that I'm not saying never, but you have to accept to wait longer
for this kind of patches, and more importantly, if you keep sending
only coding style patches, we might decide to ignore your contributions
at some point.

Regards,

Boris
