i'm sure i understand your meaning of ">" ... are you saying that "x
== NULL" is greater (preferred) to "!x" or are you saying that "x ==
NULL" should be changed to "!x" ?
i dont think the former case can be checked by checkpatch.pl, but the
latter certainly can ... but i'd be very skeptical you could get the
wider LKML audience to sign off one way or the other wrt to "x ==
NULL" vs "!x". you can certainly get people to sign off on "x == 0"
being wrong when x is a pointer.
