Did you mean "true" rather than "TRUE"?
Yes, of course. ?Commit 9f4b6a254d7a "ima: Fix bool
initialization/comparison" already addresses it. ?Please remove it
from this patch.
Is that with James?  I don't seem to have a copy, and I don't want to cause a
patch collision.

I guess also that oopsing is okay if the allocation fails.  We've run out of
memory during early boot, after all.
If the memory allocation fails, the "secure_boot" policy will not be
enabled for custom policies, but how is that "oopsing".
Sorry - I overlooked the fact that the variable is not used if it's not zero.
If it fails, there needs to be some indication of the failure, which there
currently isn't. ?Perhaps also prevent loading a custom policy.
Does it need to panic (probably fine as a small memory alloc failed)?  If it
doesn't set this policy what's the effect on things using
is_ima_appraise_enabled() - assuming we get that far?
