the code linear.c :

158              min_spacing = conf->array_sectors / 2;
159              sector_div(min_spacing, PAGE_SIZE/sizeof(struct dev_info *));

if the array size is less then 1024K and the system is 32 based,
min_spacing will be ZERO.

nope, array_sectors in in 512 byte units. So the array size has to

s/in in/ is in

be smaller than 1024 _bytes_ for min_spacing to become zero.

Thanks.
er,  "array_sectors in in 512 byte units" means  when array_sectors =
2048, the array size is actually 2048 * 512 = 1024K. Is that right?

Exactly.

when min_spacing < 1024 at line 158, it becomes zero at line 159. is that right?

Yes, that's true, provided that PAGE_SIZE is 4096 and sizeof(struct
dev_info *) is 4.
