Merge tag 'block-5.6-2020-03-13' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A few fixes that should go into this release. This contains: - Fix for a corruption issue with the s390 dasd driver (Stefan) - Fixup/improvement for the flush insertion change that we had in this series (Ming) - Fix for the partition suppor for host aware zoned devices (Shin'ichiro) - Fix incorrect blk-iocost comparison (Tejun) The diffstat looks large, but that's a) mostly dasd, and b) the flush fix from Ming adds a big comment" * tag 'block-5.6-2020-03-13' of git://git.kernel.dk/linux-block: block: Fix partition support for host aware zoned block devices blk-mq: insert flush request to the front of dispatch queue s390/dasd: fix data corruption for thin provisioned devices blk-iocost: fix incorrect vtime comparison in iocg_is_idle()
