the syscall was originally called unwhiteout.  kirk changed
it to undelete, with the intention that the semantics be
extended to include really undeleting a file (eg using a
versioning or journal-based filesystem).

it seems to be that the name undelete is ok.  would you
have both a file available for undeletion, and a whiteout
in existence at the same time?  if not, then one name is
fine - it's a namespace operator, and the operation is
defined as being one which resurrects a file with the
requested name.
