is (rscsi_disks[i].sector_size != 512) ok ?

We have a custom storage controller. It has configurable sector_size.
When configured to 1K, fdisk goes through ok. Buf mkfs gives errors shown
below.

Does Linux kernel support non 512 sector_size. Does tools
mkfs/fsck and filesystems run properly on such storage devices?
