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] Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
