Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A collection of fixes from the past few weeks that should go into 4.5. This contains: - Overflow fix for sysfs discard show function from Alan. - A stacking limit init fix for max_dev_sectors, so we don't end up artificially capping some use cases. From Keith. - Have blk-mq proper end unstarted requests on a dying queue, instead of pushing that to the driver. From Keith. - NVMe: - Update to Kconfig description for NVME_SCSI, since it was vague and having it on is important for some SUSE distros. From Christoph. - Set of fixes from Keith, around surprise removal. Also kills the no-merge flag, so it supports merging. - Set of fixes for lightnvm from Matias, Javier, and Wenwei. - Fix null_blk oops when asked for lightnvm, but not available. From Matias. - Copy-to-user EINTR fix from Hannes, fixing a case where SG_IO fails if interrupted by a signal. - Two floppy fixes from Jiri, fixing signal handling and blocking open. - A use-after-free fix for O_DIRECT, from Mike Krinkin. - A block module ref count fix from Roman Pen. - An fs IO wait accounting fix for O_DSYNC from Stephane Gasparini. - Smaller reallo fix for xen-blkfront from Bob Liu. - Removal of an unused struct member in the deadline IO scheduler, from Tahsin. - Also from Tahsin, properly initialize inode struct members associated with cgroup writeback, if enabled. - From Tejun, ensure that we keep the superblock pinned during cgroup writeback" * 'for-linus' of git://git.kernel.dk/linux-block: (25 commits) blk: fix overflow in queue_discard_max_hw_show writeback: initialize inode members that track writeback history writeback: keep superblock pinned during cgroup writeback association switches bio: return EINTR if copying to user space got interrupted NVMe: Rate limit nvme IO warnings NVMe: Poll device while still active during remove NVMe: Requeue requests on suspended queues NVMe: Allow request merges NVMe: Fix io incapable return values blk-mq: End unstarted requests on dying queue block: Initialize max_dev_sectors to 0 null_blk: oops when initializing without lightnvm block: fix module reference leak on put_disk() call for cgroups throttle nvme: fix Kconfig description for BLK_DEV_NVME_SCSI kernel/fs: fix I/O wait not accounted for RW O_DSYNC floppy: refactor open() flags handling lightnvm: allow to force mm initialization lightnvm: check overflow and correct mlc pairs lightnvm: fix request intersection locking in rrpc lightnvm: warn if irqs are disabled in lock laddr ...
