After additional research, I found the problem is actually in rtslib-fb, and made this patch (target.patch) based on the current git version of rtslib-fb and applied it to gentoo's older 2.1.62, and the problem was solved.

Thanks. Can you please also report this upstream (https://github.com/open-iscsi/rtslib-fb/issues)?

I think they already knew about it, see this commit from Feb 6 2017, which is nearly the same as the patch I made:
