Boaz Harrosh	bc47df0fa7	osdblk: Adjust queue limits to lower device's limits ... call blk_queue_stack_limits() to copy queue limits from the underline osd scsi_device. This is absolutely needed because osdblk cannot sleep when allocating a lower-request and therefore cannot be bouncing. TODO: Dynamic changes of limits to the lower device queue will not reflect in the upper driver Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>	2009-06-24 12:27:01 +03:00
Jeff Garzik	2a13877c5e	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>	2009-06-24 12:25:02 +03:00
