Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes and updates from Jens Axboe: "Some fixes and followup features/changes that should go in, in this merge window. This contains: - Two fixes for lightnvm from Javier, fixing problems in the new code merge previously in this merge window. - A fix from Jan for the backing device changes, fixing an issue in NFS that causes a failure to mount on certain setups. - A change from Christoph, cleaning up the blk-mq init and exit request paths. - Remove elevator_change(), which is now unused. From Bart. - A fix for queue operation invocation on a dead queue, from Bart. - A series fixing up mtip32xx for blk-mq scheduling, removing a bandaid we previously had in place for this. From me. - A regression fix for this series, fixing a case where we wait on workqueue flushing from an invalid (non-blocking) context. From me. - A fix/optimization from Ming, ensuring that we don't both quiesce and freeze a queue at the same time. - A fix from Peter on lock ordering for CPU hotplug. Not a real problem right now, but will be once the CPU hotplug rework goes in. - A series from Omar, cleaning up out blk-mq debugfs support, and adding support for exporting info from schedulers in debugfs as well. This is really useful in debugging stalls or livelocks.
