blkdev_nr

函数名称：lkdev_nr_zones - Get number of zones*@disk: Target gendisk* Return the total number of zones of a zoned block device. For a block* device without zone capabilities, the number of zones is always 0.

函数原型：unsigned int blkdev_nr_zones(struct gendisk *disk)

返回类型：unsigned int

参数：

类型	参数	名称
struct gendisk *	disk

zone_sectors等于blk_queue_zone_sectors(queue)

如果非blk_queue_is_zoned(queue)则返回:0

返回:get_capacity(disk)加zone_sectors减1右移log2 - log base 2 of 32-bit or a 64-bit unsigned value*@n: parameter* constant-capable log of base 2 calculation* - this can be used to initialise global variables from constant data, hence* the massive ternary operator construction* selects the (zone_sectors)位
