cross-release ftl From Chris:
"Fwiw, this isn't cross-release but us reloading the module many times, creating a whole host of new lockclasses. Even more fun is when the module gets a slightly different address and the new lock address hashes into an old lock... "I did think about a module-hook to revoke the stale lockclasses, but that still leaves all the hashed chains. "This particular nuisance was temporarily pushed back by teaching igt not to reload i915.ko on a whim."
