  I was assuming all archs used a macro for this, so I used:

$ grep 'define atomic_inc_return' asm-*/atomic.h


  But your grep could have found this:

        /* FIXME: this arch does not have atomic_inc_return */

and returned a false positive.


  What I need is a C-aware grep:

$ cgrep [--definition | --comment | --usage] atomic_inc_return asm-*/atomic.h

to search definitions, comments, and code body respectively.
