[LU-3842] handle missing crh in hsm_cdt_request_completed()

Thu, 1 Oct 2015 10:13:35 +0000

hsm_cdt_request_completed() only partially handles the case where a restore handle could not be found.

                /* give back layout lock */
                mutex_lock(&cdt->cdt_restore_lock);
                crh = hsm_restore_hdl_find(cdt, &car->car_hai->hai_fid);
                if (crh != NULL)
                        list_del(&crh->crh_list);
                mutex_unlock(&cdt->cdt_restore_lock);
                /* just give back layout lock, we keep
                 * the reference which is given back
                 * later with the lock for HSM flags */
                if (!IS_ERR(obj))
                        mdt_object_unlock(mti, obj, &crh->crh_lh, 1);
                if (crh != NULL)
                        OBD_SLAB_FREE_PTR(crh, mdt_hsm_cdt_kmem);
