You are right, set_pga seems to be a dead member. It was alive a
once, but somehow not fully removed now,
so it's safe to drop the whole if and also the struct member itself.
set_oabufs could be dropped as well.
Looking further, in the same function I also don't see any other uses of
the tested field in:
if (req->rq_oi.oi_md)
OBD_FREE_LARGE(req->rq_oi.oi_md, req->rq_buflen);
if (set->set_lockh)
lov_llh_put(set->set_lockh);
Can these be dropped as well?
thanks,
julia
