I've just booted into 4.15.0-31-generic that hit proposed, and it seems that the patch was included. From the changelog:
block: do not use interruptible wait anywhere
Just to make sure:
paulo:~/src/blktests (master)$ sudo ./check block/016
block/016 (send a signal to a process waiting on a frozen queue) [passed]
runtime 8,210s ... 10,261s
