It seems we did not consider default LMV EA when we try to shrink the EA size in RPC.

int mdt_attr_get_eabuf_size(struct mdt_thread_info *info, struct mdt_object *o)
{
.............
        /* Is it a directory? Let's check for the LMV as well */
        if (S_ISDIR(lu_object_attr(&mdt_object_child(o)->mo_lu))) {
                rc2 = mo_xattr_get(env, mdt_object_child(o), &LU_BUF_NULL,
                                   XATTR_NAME_LMV);
                         <-------------------------- we should check default LMV EA as well.
                if ((rc2 < 0 && rc2 != -ENODATA) || (rc2 > rc))
                        rc = rc2;
       }
