Zone information are reported as struct blk_zone. This implementation

Add the zoned queue limit to indicate the zoning model of a block device.

This series introduces support for zoned block devices. It integrates
earlier submissions by Hannes Reinecke, Damien Le Moal and Shaun Tancheff.
Compared to the previous series version, the code was significantly

Hi Damien,
On top of which kernel version do these patches apply? I tried to apply
the whole series to kernel v4.7 but that caused "git am" to complain ...
Thank you,

Handling of blk_mq_hw_ctx::ctxs field (de-)allocation is
confusing due to special treatment of the field introduced
in commit c3b4afca7023 ("blk-mq: free hctx->ctxs in queue's
release handler")'. Make it bit more readable by binding
hctx and hctx->ctxs (de-)allocation.
