[LU-4911] Using wrong attr inside mdd_is_subdir

Related — Sat, 9 Oct 2021 06:04:55 +0000

in mdd_is_subdir, it keeps using the same attr for all parents lookup,

static int mdd_is_parent(const struct lu_env *env,
                        struct mdd_device *mdd,
                        struct mdd_object *p1,
                        const struct lu_attr *attr,
                        const struct lu_fid *lf,
                        struct lu_fid *pf)
{
......


        for(;;) {
                /* this is done recursively, bypass capa for each obj */
                mdd_set_capainfo(env, 4, p1, BYPASS_CAPA);
                rc = mdd_parent_fid(env, p1, attr, pfid);
                .....

                p1 = parent;  <-----  p1 is changed to its parent, we should retrieve new attr here.
                 
        }

}
