Why don't you measure whether it has performance benefits? I don't understand why zram would see performance benefits and not other drivers. If it's going to be removed, then the whole interface should be removed, not just have the implementations removed from some drivers. _______________________________________________ Linux-nvdimm mailing list Linux-nvdimm@lists.01.org https://lists.01.org/mailman/listinfo/linux-nvdimm
