Due do limited maintenance window time and obvious problems with freebsd-stable@ list that day,
I went ahead and fetched releng/11.2 sources and performed source upgrade from 10.4-STABLE
to 11.2-RELEASE-p15 and it went just fine, without any additional modifications.
Then I upgraded to latest stable/11 without a problem.

Maybe we need to add something to UPDATING for stable/11 branch?
