Hi all, gcc has a warning option -Wmissing-prototypes which fires when a global function is missing a prototype declaration. This warning is important as it catches cases when that global function's prototype has been changed but its callers haven't been updated. And they should be. Currently, if enabled, this warning triggers ~1400 times for an allmodconfig build and we would like to have 0 warnings and then add that option to the main Makefile. So helping out here would be lovely! And it is very easy to do: you simply build the kernel with W=1: make -j<num_cpus+1> W=1 2>w.log choose one -Wmissing-prototypes warning in the w.log build log and fix it by including the header which has the function prototype. Or you declare the function static. If that function prototype is missing, it needs to be added, of course. For every function, one should ask oneself, is it better to make the function static and save ourselves the prototype and include file dependency - that would be the preferred solution - or if not possible, should one make the prototype visible by including the proper header so that gcc sees the prototype. This should be a good exercise for newbies who'd like to get involved into kernel development. Feel free to ask if there are any questions. Thanks! -- Regards/Gruss, Boris.
