When repeatedly using the tcrypt module (which is designed to never load successfully), the "Unloaded tainted modules" list grows forever: Unloaded tainted modules: tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 tcrypt():1 padlock_aes():1 padlock_aes():1 isst_if_mbox_msr():1 acpi_cpufreq():1 pcc_cpufreq():1 isst_if_mbox_msr():1 acpi_cpufreq():1 pcc_cpufreq():1 acpi_cpufreq():1 acpi_cpufreq():1 pcc_cpufreq():1 isst_if_mbox_msr():1 acpi_cpufreq():1 acpi_cpufreq():1 pcc_cpufreq():1 isst_if_mbox_msr():1 acpi_cpufreq():1 acpi_cpufreq():1 isst_if_mbox_msr():1 isst_if_mbox_msr():1 acpi_cpufreq():1 pcc_cpufreq():1 acpi_cpufreq():1 isst_if_mbox_msr():1 Some other modules like acpi_cpufreq() are repeated too. Maybe this check after the name comparison: mod_taint->taints & mod->taints should be: mod_taint->taints == mod->taints or shouldn't be there at all?
