The design is broken.
I don't get why it's broken. Why would the user be prevented from
enabling it at runtime?
We need to a way to totally disable it, right? Otherwise, when I configure
THP in .config, I always have THP initialized even when I pass "=never".
For me, if you don't provide such way to disable it, it is not flexible.
I meet this problem when I try to disable THP in kdump kernel, there is
no user of THP in kdump kernel, THP is a waste for kdump kernel. This is
why I need to find a way to totally disable it.
Thanks.
