This patch set fixes a couple of longstanding bugs in SCSI. The VPD patch fix a possible buffer overrun in the VPD code (only tripped if the device has a huge number of VPD pages). The other is where the status return code on our BSG interface is wrongly right shifted one place. I've had several reviewers over this one just to make sure I don't have any more stupid bugs in there The respun patch is available here: master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git The short changelog is: FUJITA Tomonori (1): bsg: fix incorrect device_status value Martin K.
