  To: James Bottomley; +Cc: linux-scsi, Mark Salyzyn


New code from the Adaptec driver.  Performance enhancement for newer
adapters.  I hope that this isn't too big for a single patch.  I believe
that other than the few small cleanups mentioned, that the changes are
all related.

- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
  requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup

Passes sparse check.
I have tested it on x86 and ppc64 machines.
Applies to scsi-misc-2.6 git tree.

This is a formatting change that makes the driver harder to read.  If
you want one argument per line, they should at least line up with the
opening bracket of the function.

This is wrong.  You're basically assuming the block layer is returning
something that goes over your segment descriptor size.

There's no API for this in SCSI, but what you should be doing is

blk_queue_max_segment_size(sdev->request_queue, 65536);

in your slave_configure routine.

OK, I changed the indentation to line up the args on the opening
bracket.

Thanks,  I reverted the aac_build_sg* code and added the
blk_queue_max_segment_size call in aac_slave_configure.

Here is the updated patch:

----
New code from the Adaptec driver.  Performance enhancement for newer
adapters.  I hope that this isn't too big for a single patch.  I believe
that other than the few small cleanups mentioned, that the changes are
all related.

- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
  requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup

Passes sparse check.
I have tested it on x86 and ppc64 machines.
Applies to scsi-misc-2.6 git tree.
