I suggest to omit leading underscores from such identifiers.

I was gonna apply this change, but I ack'd existing files and I find
that all of them include leading underscores, including some very
recently added files like net/core/page_pool_priv.h.

I would prefer to stick to existing conventions if that's OK, unless
there is widespread agreement to the contrary.

Under which circumstances would you become interested to reduce development risks
also according to undefined behaviour?
