[PATCH 0/4] scsi: increase upper limit for max_sectors

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

This patchset increases the SCSI mid level's limitation for max_sectors
upto the block layer's limitation for max_hw_sectors, and enables the
scsi_debug driver to request read/write commands with huge transfer
length.  This also includes a few fixes for the problems which can be
caused by huge max_sectors in the block layer.

Akinobu Mita (4):
  block: fix BLKSECTGET ioctl when max_sectors is greater than USHRT_MAX
  block: fix SG_[GS]ET_RESERVED_SIZE ioctl when max_sectors is huge
  scsi: increase upper limit for max_sectors
  scsi_debug: allow huge transfer length for read/write commands
