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 block/compat_ioctl.c | 6 ++++-- block/ioctl.c | 5 ++++- block/scsi_ioctl.c | 15 +++++++++++---- drivers/scsi/scsi_debug.c | 6 +++--- drivers/scsi/sd.c | 5 +---- drivers/scsi/sg.c | 17 +++++++++++++---- include/scsi/scsi_host.h | 4 ++-- 7 files changed, 38 insertions(+), 20 deletions(-) Cc: Jens Axboe <ax...@kernel.dk> Cc: "James E.J.
