Sorry for the late response. Just am back from vacation.
Tomo please hold with these patches a bit longer the
Tree is not ready for it.
Mainly you will totally break USB storage mid-layer.
There is one converted USB driver - microtek.c - that is
currently broken. This is because usb mid-layer still issues
a synchronous REQUEST_SENSE with use_sg == 0.
(And still bangs all over scsi_cmnd members) I have a
complete and somewhat tested solution for the USB stack
and all the drivers. as well as lots of other drivers
(see list below). I will submit them group by group during
this week and next week. The reason I did not release them
yet is because I did not want to do this before the vacation
and not be available for debugging.
Some of the files I have patches for are:

If any of these are obsolete and should be removed please
say so. Save me the work to submit them.
Thanks
