Paddle use CamelCase naming convention. For example, all the functions of pool_op.cc use CamelCase naming convention, but pool_mkldnn_op.cc use gethash, not GetHash. Could you please go over all the MKLDNN related codes in fluid version, and correct it? @jczaja @kbinias @mozga-intel @pzelazko-intel @tpatejko
