Hi all,
This converts md to the atomic queue limits update API. It passes
the mdadm and lvm2 test suites without regressions.
Changes since v3:
- drop the already merged core block layer and dm patches
- sort out a minor conflict after rebasing to the latest block tree
Changes since v2:
- drop drbd from this series again for now as we've not made any
review progress
- keep the NULL gendisk checks for DM-mapped MD devices, and add a few
helpers to better document and abstract them
- use mddev_suspend instead of blk_mq_freeze_queue around updating
io_opt
Changes since v1:
- a few kerneldoc fixes
- fix a line remove after testing in raid0
- also add drbd
