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()
