Hi Tejun
I've inspected all scsi touching patches and refrained from comments
on the simple rename bunch. They all look very good accept that one
place. (which will effect 2 patches)
There are few more places that can use blk_end_request_all() after
these changes.
(The same internet outage on this reply)
Thanks
Boaz
