It's a huge mess. "__" prefix is just so ambiguous I think it just
shouldn't be used or prolifierated, and it usually breaks Rusty Russells
API rules times over.

Consider __set_bit() from <linux/bitops.h>, used all over the place,
in contrast with set_bit() for example, what does "__" represent in
this context that makes __set_bit() different from set_bit()?

It means "non-atomic"...

How does a random contributor know this?

Yeah, you guess it. By the token of "everybody knows that".
(Grep, google, repeat for the number of contributors to the kernel.)

I was considering to send a script to Torvalds to just change all
this to set_bit_nonatomic() (etc) but was hesitating because that
makes the name unambiguous but long. I think I stayed off it
because changing stuff like that all over the place creates churn
and churn is bad.

Yours,
Linus Walleij
