Colin Percival e07113d65c Use DEV_BSIZE byte sectors instead of PAGE_SIZE byte sectors for ... swap-backed memory disks. This reduces filesystem allocation overhead and makes swap-backed memory disks compatible with broken code (dd, for example) which expects to see 512 byte sectors. The size of a swap-backed memory disk must still be a multiple of the page size. When performing page-aligned operations, this change has zero performance impact.
