No, you have not addressed all my comments, you know that you have not
addressed all my comments so you should not have written that you have
addressed all my comments. This patch series not only introduces ugly
changes in the request queue freeze mechanism but it also introduces an
unacceptable race condition between blk_get_request() and request queue
cleanup.

BTW, you don't have to spend more time on this patch series. I have
implemented an alternative and much cleaner approach to fix SCSI device
suspend. I'm currently testing that patch series.
