some combinations of filesystem and block device (at least vfat on mmc)
yield -EROFS instead of -EACCES when the device is read-only. Retry

The Pinctrl configuration has already been applied, so the only
missing piece of the DT puzzle is for a board's DTB to enable
the nodes.

Yes, I am. Don't get me wrong - I'm all for not enabling code which is
unused - I'm just questioning the actual usage case here.

Currently, both blk_queeu_bypass_start() and blk_mq_freeze_queue()
skip queue draining if bypass_depth was already above zero. The
assumption is that the one which bumped the bypass_depth should have
performed draining already; however, there's nothing which prevents a
new instance of
blk-mq uses a percpu_counter to keep track of how many usages are in
flight. The percpu_counter is drained while freezing to ensure that
no usage is left in-flight after freezing is complete.

Hello, Jens.
While reading through blk-mq, I spotted several issues and this
patchset addresses them. The biggest one is how freezing is
implemented. Coupling it with bypassing doesn't seem to work well and
there's a subtle bug in the perpcu switch implementation.
I don't think open-coding
Keeping __blk_mq_drain_queue() as a separate function doesn't buy us
anything and it's gonna be further simplified. Let's flatten it into
its caller.
This patch doesn't make any functional change.

blk_mq freezing is entangled with generic bypassing which bypasses
blkcg and io scheduler and lets IO requests fall through the block
layer to the drivers in FIFO order. This allows forward progress on
IOs with the advanced features disabled so that those features can be
configured or altered
blk_mq_stop_hw_queue() has the following two issues.
* BLK_MQ_S_STOPPED should be set before canceling the work items;
otherwise, a new instance may proceed beyond STOPPED checking
inbetween.
* cancel_delayed_work() doesn't do anything to work instance already
executing. Use
