My mistake. I was made aware of it earlier today and I'm working on a patch. Surprised we didn't see any reports of this in -next. It's been in there for a while.

People were complaining about excessive mempool usage with the block integrity bits enabled (thanks to MD and DM allocating a bioset per device to prevent deadlocks). Making allocation conditional meant we had to deal with memory allocation errors in the setup path. I tested various combinations of on and off but apparently not all off.
