Subjectlustre: question about lov_request.c

The function lov_finish_set in
drivers/staging/lustre/lustre/lov/lov_request.c contains the code:

if (set->set_pga) {
int len = set->set_oabufs * sizeof(*set->set_pga);
OBD_FREE_LARGE(set->set_pga, len);

If I change the call to OBD_FREE_LARGE to kvfree, then len is not useful
any more. But actually, at least with grep, I can't find anywhere that
either the set_pga field or the set_oabufs field is set. Am I missing
something, or can the whole if be removed? Can these two fields go too?
