EAGAIN comes from ofd_lvbo_init():

		/* Object could be recreated during the first
		 * CLEANUP_ORPHAN request. */
		if (rc == -ENOENT) {
			seq = fid_seq(&info->fti_fid);
			oseq = ofd_seq_load(env, ofd, fid_seq_is_idif(seq) ?
					    FID_SEQ_OST_MDT0 : seq);
			if (!IS_ERR_OR_NULL(oseq)) {
				if (!oseq->os_last_id_synced)
					rc = -EAGAIN;
				ofd_seq_put(env, oseq);
			}
		}

the code was added in ~~LU-11765~~ which sent EAGAIN instead of ENOENT expecting EAGAIN led to a resend. it happens indeed for enqueue due to (a hack?) cl_glimpse_size0(), but not for others.
