I see the problem; inode_lock isn't currently an exported symbol, and I generally don't compile ext4 as a module, so I didn't notice the problem. The patch in question is a debugging patch that is never meant for mainline or a for-stable series, so the simplest thing to do for now is just to revert the patch. I'll look into a module-friendly way of accomplishing the same goal.
