: This is not sensible. style(9) says right at the start that it "[...] 
: specifies the preferred style for kernel source files [...]". The 
: preferred style would be to use ANSI function declarations - what else 
: is there to say? There is no point in adding more when less is sufficient.

Actually, in a style guide, there is a point.

Adding language that says we're actively removing K&R-style
declarations and definitions reinforces this point and explains to
people what's going on when they see this in the tree today.

This would have been understandable by some folks if I'd left it at
the first paragraph, but by adding the second it becomes clear the
reasoning behind my post.
