Damien,

> Initialize the seq_zones_bitmap, seq_zones_wlock and nr_zones fields
> of the disk request queue on disk revalidate. As the seq_zones_bitmap
> and seq_zones_wlock allocations are identical, introduce the helper
> sd_zbc_alloc_zone_bitmap(). Using this helper, reallocate the bitmaps
> whenever the disk capacity (number of zones) changes.
