See the following issue for context:
FAULT_INJECTION: fail copy_to/from_user
https://bugzilla.kernel.org/show_bug.cgi?id=208461

Similarly we could fail all LSM hooks. LSM can fail all of them, but testing this systematically with an actual LSM is hard.

There's a patch series that implements this feature
