Sure, no problem, except that UACCESS refers to different things.
I'd probably call it UIOVEC, if we want a name that does refer to the
same somewhere (*BSD).  If anything, it's generalization of copyin/copyout
for non-userland destinations/sources; uaccess answer to (subset of) the
same problem would be set_fs()/get_fs() and the fewer we have left of that,
the better...
