I have tested against libata and scsi_debug for disks. There are slight
changes, so someone with a tape device should test the patches, but Kai
since Kai did all the debugging last round I have not made many changes.
We will probably hit many problems with LLDs using low max_hw_sectors,
because they have not been converted to export their real values on the
host template so I think these patches should sit in scsi-misc for a
good deal of time.
looks like linus is closing the big merge window for 2.6.15, so we won't
be able to get this in fully. What do you thing about getting in the
infrastructure at least, that is patches: 1,3,6,7 for 2.6.15 and the rest
afterwards, after the max_sectors thing has settled a little?
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?
