if two kernel developers agree that tabs-only alignment of arglists is not 
necessary, then my guess is that the CodingStyle document is broken and 
needs to be fixed. Quote from Documentation/CodingStyle:

That's OK, we all do.  You've probably been told by your long-time 
Unix user helper that "GNU emacs" automatically formats the C sources for 
you, and you've noticed that yes, it does do that, but the defaults it 
uses are less than desirable (in fact, they are worse than random typing - 
an infinite number of monkeys typing into GNU emacs would never make a 
good program).

So, you can either get rid of GNU emacs, or change it to use saner
values.  To do the latter, you can stick the following in your .emacs 
file:

If emacs' style is OK then why all this inflamatory talk is needed, and 
why is a patch proposed? The only thing needed is to use the "linux" 
c-style.

Thanks,
Dimitris
