Allocating zone write plugs using a struct kmem_cache does not guarantee that enough write plugs can be allocated to simultaneously write up to the maximum number of active zones of a zoned block device. Avoid any issue with memory allocation by using a mempool with a size equal to the disk maximum number of open zones or maximum number of active zones, whichever is larger. For zoned devices that do not have open or active zone limits, the default 128 is used as the mempool size. If a change to the zone limits is detected, the mempool is resized in blk_revalidate_disk_zones().

Why isn't this part of the previous patch?
