This patch series didn't change this behavior. The same kind of macros are used for CONFIG_MODULE_SIG_KEY. > > I used the script in 10/10 to test this, which is another > reamark: the patches are in invalid order, as you need to > apply 10/10 before you can test 8/10. I'll move patch 10/10 earlier but this kind of formatting was already required (but silently ignored) for this option to be really taken into account. Only the kernel code was available to understand how to effectively create such hash. > > /Jarkko >
