Provide kfence_is_enabled() helper, only load kfence_test module when kfence is enabled.What's wrong with the current behavior? I think we need at least some way to tell the developer that KFENCE does not work, and a failing test seems to be the perfect one.If the kfence is not enabled, eg kfence.sample_interval=0, kfence_test spend too much time, and all tests will fails. It is meaningless. so better to just skip it ;)
But what is your usecase? I'd like to avoid the export of a new function that is pretty much unused. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
