Tainting is used for distris to verify whether the customer
still has support and shows up in kernel oopses, dmesg, etc.
It can also be useful for bugzilla logs, so that developers
quickly get an idea that the user has done something he
should not do.
With
grep TAINT include/linux/kernel.h
you see possible reasons to taint a kernel.
Adding:
add_taint(TAINT_OVERRIDDEN_ACPI_TABLE);
when the user successfully modified an AML method should
get added.
Thanks,
Thomas
