Then we'd need two features. One modules removed, and another which limits this to only tainted modules. On kernel-ci systems where I try to reproduce issues with fstests or blktests I might be unloading a module 10,000 times, and so for those systems I'd like to disable the tracking of all modules removed, otherwise we'd end up with -ENOMEM eventually.

It is tricky but I have been trying to correct issues along that path and given that fstests and blktests uses it heavily I want to start dispelling the false narrative that this is not a common use case.

Yes!
