The RFC patches above from May 31st weren't merged because I thought you
where going to send out a second series..
https://www.spinics.net/lists/target-devel/msg15505.html
Since that hasn't been the case, I'll go ahead and merge the bugfixes in
patches #1-6 for v4.13 now. :)
Please resend patches #7-13 as post v4.13 items at your earliest
convenience.
Apologies for the confusion.
