Subject: lustre: question about lov_request.c

Hello,

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?

thanks,
julia
