Yeah, that would be a good idea.

How about we drop the @atomic parameter and simply use @duplicates to
figure out whether to perform duplicate detection, which we should
note in the comment of efivar_init() cannot be performed atomically.
Bonus points if someone can clean up the code flow too.

Otherwise, efivar_init() is done while holding a spinlock.
