[PATCH v2 0/2] vhost-scsi: Fix IO hangs when using windows

The following patches were made over Linus's tree and fix an issue
where windows guests will send iovecs with offset/lengths that result
in IOs that are not aligned to 512. The LIO layer will then send them
to Linux's FS/block layer but it requires 512 byte alignment, so
depending on the FS/block driver being used we will get IO errors or
hung IO.

The following patches have vhost-scsi detect when windows sends these
IOs and copy them to a bounce buffer. It then does some cleanup in
the related code.
