A handful?

$ git grep "return container_of" | wc -l
1856

I'm like Donald Trump because I must have really small hands compared
to the rest of y'all.

I would prefer to apply these sorts of patches unless it causes an
issue...  Functions *are* better than macros.  It's a minor improvement,
but this is staging and we make tons minor style changes.  It's part of
the blessing and curse of being in staging...
