	dnnl_memory_extra_flag_compensation_conv_s8s8

Indicates the weights have an additional buffer, that depends on the ``compensation_mask``.

For instance, in 4D case with the compensation mask equals (1 << 0) the additional buffer would consist of OC values: O[oc : 0,OC] = -128 \* SUM(ic : 0,IC; kh : 0,KH; kw : 0,KW){ weights(oc, ic, kh, kw) }
