Merge branch 'for-4.7/drivers' of git://git.kernel.dk/linux-block
Pull block driver updates from Jens Axboe: "On top of the core pull request, this is the drivers pull request for this merge window. This contains: - Switch drivers to the new write back cache API, and kill off the flush flags. From me. - Kill the discard support for the STEC pci-e flash driver. It's trivially broken, and apparently unmaintained, so it's safer to just remove it. From Jeff Moyer. - A set of lightnvm updates from the usual suspects (Matias/Javier, and Simon), and fixes from Arnd, Jeff Mahoney, Sagi, and Wenwei Tao. - A set of updates for NVMe: - Turn the controller state management into a proper state machine. From Christoph. - Shuffling of code in preparation for NVMe-over-fabrics, also from Christoph. - Cleanup of the command prep part from Ming Lin. - Rewrite of the discard support from Ming Lin. - Deadlock fix for namespace removal from Ming Lin. - Use the now exported blk-mq tag helper for IO termination. From Sagi. - Various little fixes from Christoph, Guilherme, Keith, Ming Lin, Wang Sheng-Hui. - Convert mtip32xx to use the now exported blk-mq tag iter function, from Keith" * 'for-4.7/drivers' of git://git.kernel.dk/linux-block: (74 commits) lightnvm: reserved space calculation incorrect lightnvm: rename nr_pages to nr_ppas on nvm_rq lightnvm: add is_cached entry to struct ppa_addr lightnvm: expose gennvm_mark_blk to targets lightnvm: remove mgt targets on mgt removal lightnvm: pass dma address to hardware rather than pointer lightnvm: do not assume sequential lun alloc. nvme/lightnvm: Log using the ctrl named device lightnvm: rename dma helper functions lightnvm: enable metadata to be sent to device lightnvm: do not free unused metadata on rrpc lightnvm: fix out of bound ppa lun id on bb tbl lightnvm: refactor set_bb_tbl for accepting ppa list lightnvm: move responsibility for bad blk mgmt to target lightnvm: make nvm_set_rqd_ppalist() aware of vblks lightnvm: remove struct factory_blks lightnvm: refactor device ops->get_bb_tbl() lightnvm: introduce nvm_for_each_lun_ppa() macro lightnvm: refactor dev->online_target to global nvm_targets lightnvm: rename nvm_targets to nvm_tgt_type ...
