Hi all,

this series is on top of the scsi_request changes in Jens' tree and
further improves the handling of the sense buffer.

Sorry, but I'm feeling really daft: which scsi_request changes?

That is the "split scsi passthrough fields out of struct request"
series.

To be found in which tree?

Jens' for-next tree, as mentioned above.

Have we audited all drivers to _not_ do DMA into the sense buffer?
By first glance some still do, so they'll break horribly when moving the
sense buffer onto the stack ...

With the above series the sense buffer is allocate by the driver,
and they will always DMA into that.
