I had another look at your latest patches and they are still quite sloppy: 
you never ran them through checkpatch.pl, right? Tons of warnings, quite a 
few of which are legitimate.

These are all basic kernel hacking 101 mistakes you commited and we are 
already into version 9 of your patch-set ...

Having to point out trivial errors in your patches again and again is not 
a very efficient use of my time, frankly.

Thanks,
