These are fixes for zoned btrfs.

Patch 01 fixes the type of a zone sector variable.  

Patch 02 moves the superblock location to address based.

Patch 03 fixes zone_unusable acconting when a block group is read-only.

v1 -> v2:
 - Move the type fix patch to be the first one
 - Fix the type of variable instead of casting
 - Introduce #define's for the superblock zone locations and maximum zone
   size

Naohiro Aota (3):
  btrfs: zoned: use sector_t to get zone sectors
  btrfs: zoned: move superblock logging zone location
  btrfs: zoned: do not account freed region of read-only block group as
    zone_unusable
