New rule: before you send some optimization, you need to have NUMBERS.
I tried to underline that it's not a performance optimization at my best.
If it's not about performance, then it damn well shouldn't be 90% inline functions in a header file.
If it's a helper function, it needs to be a real function elsewhere. Not this:
include/linux/find_atomic.h | 324 +++++++++++++++++++
because either performance really matters, in which case you need to show profiles, or performance doesn't matter, in which case it damn well shouldn't have special cases for small bitsets that double the size of the code.
