Strangely, I can't reproduce it either on my original branch (v4.12 with this patch), or torvalds/master (this patch is already merged with your renaming) Also I'm enabling CONFIG_BTRFS_DEBUG, so when the btrfs_warn() is triggered, it should cause the test case to fail. However I tried all btrfs/09*, nothing happened. Is some other out-of-tree patch causing the problem? If so, which branch are you testing? I think I could help to fix it.
