我在理解MTD驱动程序中的一些代码时遇到问题

#define ROUNDUP(x, y)       ((((x)+((y)-1))/(y))*(y))
...
static struct mtd_partition my_parts[] =
{
   {
      .name = "boot",
      .size = 0,
      .offset = 0,
      .mask_flags = MTD_WRITEABLE
   },
   {
      .name = "linux",
      .size = 0,
      .offset = 0
   },
   {
       .name = "rootfs",
       .size = 0,
       .offset = 0,
       .mask_flags = MTD_WRITEABLE
   },
   {
       .name = "nvram",
       .size = 0,
       .offset = 0
   },
   {
       .name = 0,
       .size = 0,
       .offset = 0
   }
}
...

i = (sizeof(bcm947xx_parts)/sizeof(struct mtd_partition)) - …
