Hi Martin,
I replied in the following link for James's concerns:
https://marc.info/?l=linux-block&m=151074751321108&w=2
The fact is that use-after-free can't avoided at all, no matter if
we set the cmnd to NULL before calling free, that means we have to
handle use-after-free well in scsi_show_rq(), so we don't need to
touch the free code.
So V4 is well enough for merge, IMO.
Thanks,
Ming
