Hi Jens, A couple of patches for 4.9. We are preparing the pblk target for upstream, but it will have to wait for at least a cycle before it is ready. Geert and Arnd sent two fixes. One check for DMA and another for missing a device_add check. Simon added sysfs support to LightNVM. It allows the user to inspect the geometry of a device through sysfs. As NVMe device driver integrates with blk-mq, it also exposes the blk-mq sysfs structure. I added a couple of plumbing patches to enable sysfs. It mainly refactors nvme and null_blk to take control over nvm_dev and replaces the gendisk parameter in blk_mq_(un)register_disk() with device and the associated request queue. Please pick up. The patches are available here: https://github.com/OpenChannelSSD/linux.git for-jens Thank you, Matias Arnd Bergmann (1): lightnvm: propagate device_add() error code Geert Uytterhoeven (1): lightnvm: NVM should depend on HAS_DMA Matias Bjørling (4): nvme: refactor namespaces to support non-gendisk devices null_blk: refactor to support non-gendisk devices blk-mq: register device instead of disk lightnvm: control life of nvm_dev in driver Simon A.
