This patchset aims to fix several problems related to T10-PI support.
These patches can be applied on top of Sagi's [v1] Simlify dif_verify
routines and fixup fileio protection information code patchset.
Akinobu Mita (4):

target:
sbc_dif_generate() and sbc_dif_verify() assume that each SG element
for data transfer memory doesn't straddle the block size boundary.
However, when using SG_IO ioctl, we can choose the data transfer memory
which doesn't satisfy that alignment requirement.
This change detects such cases and
Now we can generate correct PI for WRITE SAME command, so it is
unnecessary to disallow WRITE SAME when protection info is enabled.

For WRITE SAME, data transfer memory only contains a single block but
protection information is required for all blocks that are written by
the command.
This makes sbc_dif_generate() work for WRITE_SAME.

This works around a issue with qnap iscsi targets not handling large IOs
very well.
The target returns:

The fusion HBAs don't really use the instance template like the other
variants, as it branches off at a much higher level. So instead of
trying to squeeze megasas_fire_cmd_fusion into the wrong calling
convention call it locally with argument data types that match what
is passed.
