I suspect that this line:
for (action = 0; action < ARRAY_SIZE(kobject_actions); action++) {
in lib/kobject_uenvent.c:kobject_action_type() combined with the fact that
kobject_actions[] does *not* actually match the enum regardless of the comment
above it, result in it being superfluous.
Figuring out why is left as an exercise for the student.
Oh, and if I had a dollar for every time I've been surprised by creative abuse
of
the cpp ## operator... :)
