If you merge #3 you need the late #11
http://marc.theaimsgroup.com/?l=linux-scsi&m=113149038422831&w=2
It is up to Jens though since I am really digging deep into the block
layer code in #3 and #6 may need to be fixed for SG_IO sr commands. I
can rediff them if you they do not merge correctly. I noticed the block
layer move code is now merge in scsi-misc.
Oh yeah was my last max_sectors close
http://marc.theaimsgroup.com/?l=linux-scsi&m=113147482216587&w=2
or did it need work, or do I just need to get LLD writers to set their
sht->max_sectors correctly?
