I fully agree with Jan.

And, as him, I also think you can update the header comments at the
beginning of both rbtree.c and rbtree.h files, as soon as you mention
that in the changelog.

*HOWEVER*, about this change, in both .c and .h:

This comes from 443701ef "Replace FSF street address with canonical
URL" (check with `git blame xen/common/rbtree.c'), and I think we
should leave this alone (i.e., keep the url, and not change back to the
physical address).

I understand it then will be a difference between our rbtree.{c,h} and
Linux's ones, but I think it's one difference it's worth living with
(and, honestly, I really don't expect this specific thing to cause much
issues in future 'backports' from Linux).

If others agree on this too, that would mean you basically would let
the header comment of rbtree.c alone, while in rbtree.h, you "just" add
the commented API usage example functions.
