A couple of patches for 2.0 support for the lightnvm subsystem. They form the basis for integrating 2.0 support. For the rest of the support, Javier has code that implements report chunk and sets up the LBA format data structure. He also has a bunch of patches that brings pblk up to speed. The first two patches is preparation for the 2.0 work. The third patch implements the 2.0 data structures, the geometry command, and exposes the sysfs attributes that comes with the 2.0 specification. Note that the attributes between 1.2 and 2.0 are different, and it is expected that user-space shall use the version sysfs attribute to know which attributes will be available. The last patch implements support for using the nvme namespace logical block and metadata fields and sync it with the internal lightnvm identify structures. Changes since v1: - pr_err fix from Randy. - Address type fix from Javier. - Also CC the nvme mailing list.
