He should consider not sending them at all. It's up to maintainers and 
the developers involved with that code whether the small details that 
checkpatch flags are important or not at a given point in the patch 
cycle.

For example i use checkpatch all the time and i think it's a fantastic 
tool, still i dont want another nuisance layer on lkml interfering with 
the patch flow.

If a patch gets so far in the patch cycle that i'm thinking about 
merging it, i might fix the checkpatch failures myself (often they are 
trivial), and i might warn frequent contributors about repeat patterns 
of small uncleanlinesses - or i might bounce the patch back to the 
contributor. I also ignore certain classes of checkpatch warnings.

What Daniel is doing is basically a semi-mandatory checkpatch layer on 
lkml and that's both a distraction and harmful as well. We dont need a 
"checkpatch police" on lkml. We want an open, reasonable, human driven 
patch process with very little buerocracy and no buerocrats.
