Merge branch 'for-4.5/nvme' of git://git.kernel.dk/linux-block
Pull NVMe updates from Jens Axboe: "Last branch for this series is the nvme changes. It's in a separate branch to avoid splitting too much between core and NVMe changes, since NVMe is still helping drive some blk-mq changes. That said, not a huge amount of core changes in here. The grunt of the work is the continued split of the code" * 'for-4.5/nvme' of git://git.kernel.dk/linux-block: (67 commits) uapi: update install list after nvme.h rename NVMe: Export NVMe attributes to sysfs group NVMe: Shutdown controller only for power-off NVMe: IO queue deletion re-write NVMe: Remove queue freezing on resets NVMe: Use a retryable error code on reset NVMe: Fix admin queue ring wrap nvme: make SG_IO support optional nvme: fixes for NVME_IOCTL_IO_CMD on the char device nvme: synchronize access to ctrl->namespaces nvme: Move nvme_freeze/unfreeze_queues to nvme core PCI/AER: include header file NVMe: Export namespace attributes to sysfs NVMe: Add pci error handlers block: remove REQ_NO_TIMEOUT flag nvme: merge iod and cmd_info nvme: meta_sg doesn't have to be an array nvme: properly free resources for cancelled command nvme: simplify completion handling nvme: special case AEN requests ...
