I'm not in favor or against either of options: it comes down to the
coding style of the project - sticking to same one makes code
cohesive (by project I mean Linux-kernel).

However, to switch entire catpt to reversed xmas tree, more code changes
are required (even this very function is an example of that). Leaving as
is in this update while considering the subject in other series might be
the better outcome.
