This is the same as last time as it was posted, but with Kai's patches
merged and we now pass the bytes value to scsi_execute_async.
This does not work "out of the box". The changes in st are almost the
same ones than before but the world around st has changed ;-) This has
revealed at least one bug in st that is fixed by the patch at the end
of this
ok thanks.
message. After this patch some simple tests succeed but there seem to
be still problems with larger requests. I don't have time to continue
debugging just now but I should be able to post more results during
this weekend.
Was there a oops or lockup or any debug output you can send me? I will
try some more large request tests with scsi_debug. You also have to
compile your kernel with SCSI_MAX_PHYS_SEGMENTS == 255 to get larger
requests now.
Oh yeah I put the patches Christoph asked me to make, and changes that
Jens and Pat Mansfield asked for, and a patch to increase
SCSI_MAX_PHYS_SEGMENTS here
http://www.cs.wisc.edu/~michaelc/block/use-sg/v11/
They were made against a scsi-misc tree I got today. But I was not
actually able to test against that tree becuase the current git trees
(scsi-misc, linux-2.6.git, etc) do not boot for me.
