Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe: "Remember about a week ago when I sent the last pull request for 4.1? Well, I lied. Now, I don't want to shift the blame, but Dan, Ming, and Richard made a liar out of me. Here are three small patches that should go into 4.1. More specifically, this pull request contains: - A Kconfig dependency for the pmem block driver, so it can't be selected if HAS_IOMEM isn't availble. From Richard Weinberger. - A fix for genhd, making the ext_devt_lock softirq safe. This makes lockdep happier, since we also end up grabbing this lock on release off the softirq path. From Dan Williams. - A blk-mq software queue release fix from Ming Lei. Last two are headed to stable, first fixes an issue introduced in this cycle" * 'for-linus' of git://git.kernel.dk/linux-block: block: pmem: Add dependency on HAS_IOMEM block: fix ext_dev_lock lockdep report blk-mq: free hctx->ctxs in queue's release handler

Saying Y here will allow you to use a contiguous range of reserved
memory as one or more persistent block devices.
