A lot of those whitespace noises are the documented preferred
style in CodingStyle.
It's your choice to modify them or not.
Here's what some of those whitespaces elements are that
checkpatch offers to make more CodingStyle conformant via:
$ scripts/checkpatch.pl -f --fix --strict \
--types=spacing,pointer_location,code_indent,space_before_tab \
fs/binfmt_misc.c
$ mv fs/binfmt_misc.c.EXPERIMENTAL-checkpatch-fixes fs/binfmt_misc.c
