7 a smaller logical block size on a device with a larger logical block
11 Supported emulated logical block sizes 512, 1024, 2048 and 4096.
13 Underlying block size can be set to > 4K to test buffering larger units.
17 ----------------
18 <dev path> <offset> <emulated sectors> [<underlying sectors>]
23 Full pathname to the underlying block-device,
24 or a "major:minor" device-number.
25 <offset>:
29 Number of sectors defining the logical block size to be emulated;
35 Number of sectors defining the logical block size of <dev path>.
37 If not provided, the logical block size of <dev path> will be used.
42 Emulate 1 sector = 512 bytes logical block size on /dev/sda starting at
43 offset 1024 sectors with underlying devices block size automatically set:
47 Emulate 2 sector = 1KiB logical block size on /dev/sda starting at
48 offset 128 sectors, enforce 2KiB underlying device block size.
