Currently the geometry of an OCSSD is enumerated using a two step approach: First, nvm_register is called, the OCSSD identify command is issued, and second the geometry sos and csecs values are read either from the OCSSD identify if it is a 1.2 drive, or from the NVMe namespace data structure if it is a 2.0 device. This patch recombines it into a single step, such that nvm_register can use the csecs and sos fields independent of which version is used. This enables one to dynamically size the lightnvm subsystem dma pool.
