osdblk: a Linux block device for OSD objects
Submitted driver exports a block device of the form /dev/osdblkX,
where X is a decimal number.
It does that by mounting a stacking block device on top
of an osd object. For example, if you create a 2G object
on an OSD device, you can then use this module to present
that 2G object as a Linux block device.
See inside patch for exact documentation.
[Sitting at linux-next helped fix proper Kconfig dependency
for this driver, thanks to Randy Dunlap]
