[PATCH 0/7] scsi: Fix transfer length 0 for 6-byte r/w commands

[Akinobu Mita <akinobu.mita@gmail.com>]

For 6-byte r/w commands, transfer length 0 means 256 blocks of data,
not 0 block.

But some drivers consider transfer length 0 as 0 block.
Fortunately, the scsi disk driver sets up 10-byte r/w commands for
256 blocks of data instead of 6-byte r/w commands.  So this could be
an issue when SCSI commands are issued by SG_IO ioctl.
