That's probably not a horrible idea, at least when we're talking a
reasonable number of users (ie when we're talking "tens of users" like
strlcpy is now).
We should probably generally rename functions much more aggressively
any time the "signature" changes.
We've had situations where the semantics changed but not enough to
necessarily trigger type warnings, and then renaming things is just a
good thing just to avoid mistakes. Even if it's temporary and you plan
on renaming things back.
And with a coccinelle script (that should be documented in the patch)
it's not necessarily all that painful to do.
