apologies if this is an inappropriately trivial question but this has been bugging me for a while. what is the deal with "inline"?
first, there appear to be three possible ways of specifying an inline routine in the kernel source:
$ grep -r "static inline " . $ grep -r "static __inline__ " . $ grep -r "static __inline " .
i vaguely recall that this has something to do with a distinction between C99 inline and gcc inline and trying to avoid a clash between the two, but i'm not going to put any money on that. but the confusion probably explains why so many people insist on creating new macros to represent inline:
$ grep -r "#define.*inline" .
is there a simple explanation for how to *properly* define inline routines in the kernel? and maybe this can be added to the CodingStyle guide (he mused, wistfully).
