Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "Sending this a bit sooner than I otherwise would have, as a fix in the merge window had some unfortunate issues and side effects for some folks. This contains: - Fixes from Jan for the bdi registration/unregistration. These have been tested by the various parties reporting issues, and should be solid at this point. - Also from Jan, fix for axonram gendisk registration. - A stable fix for zram from Johannes. - A small series from Ming, fixing up some long standing issues with blk-mq hardware queue kobject initialization and registration. - A fix for sed opal from Jon, fixing a nonsensical range check and some set-but-not-used variables. - A fix from Neil for a long standing deadlock issue for stacking device drivers. With this in place, dm/md don't have to work around the issue anymore, and can be properly fixed up" * 'for-linus' of git://git.kernel.dk/linux-block: axonram: Fix gendisk handling blk: improve order of bio handling in generic_make_request() Revert "scsi, block: fix duplicate bdi name registration crashes" block: Make del_gendisk() safer for disks without queues bdi: Fix use-after-free in wb_congested_put() block: Allow bdi re-registration block/sed: Fix opal user range check and unused variables zram: set physical queue limits to avoid array out of bounds accesses blk-mq: free hctx->cpumask in release handler of hctx's kobject blk-mq: make lifetime consistent between hctx and its kobject blk-mq: make lifetime consitent between q/ctx and its kobject blk-mq: initialize mq kobjects in blk_mq_init_allocated_queue()
