Sure, and honestly, I understand what 0444 is better than seeing:

  S_IRUSR | S_IRGRP | SIROTH

Heck, 0444 is more understandable to me than S_IRUGO, because honestly, those
macros are just as cryptic as 0444 is. Working with Unix/Linux systems since
1991, I understand the octo numbers very well. And I'm sure most other people
do to. Any file that I'm Cc'd on here will get an automatic NAK from me.

Yes, it's a very good way to be added to everyone's /dev/null folder too. Each
subsystem should have one patch that covers all its files. Not a patch per
file!

What? Is Intel now give extra bonuses for commit numbers?

Sorry, but I'm a little grumpy when my phone starts popping like a popcorn
machine while I'm having my breakfast because of these silly emails.
