I and my lieutenants are most likely polite enough to avoid using a word like nuisance, but I think you will hear words like code churn, especially if such a change affects too many places and conflicts with too many patches that are still in the queue to be merged. IOW, you need to be careful. The general rule of thumb is to do such a clean-up before you start to work on something of substance. Your series may look like this: * [Patch 1/2] hello.c: tighten constness and scope Many functions in this file do not have to be called from other files, and goodmorning() takes "char *" parameters but does not modify them in any way (others like goodafternoon() and goodevening() are already correct in this regard, both taking "const char *" parameters). Make all of tese functions file scope static, and tighten constness to the parameters to gootmorning(). By making their function signatures compatible, this change will help the next patch that refactors the three greeting functions. * [Patch 2/2] hello.c: refactor goodmorning(), goodafternoon() and goodnight() These functions do mostly the same thing; implement a common helper function greeting() and share code among them. Otherwise, unless the tree is really quiet, a patch that is only clean-up and nothing else will have a high maintenance-cost vs reward ratio, and needs to be split and timed carefully. A patch that applies cleanly to master and then the result merges cleanly to both next and pu would be Ok even if you do not add any value other than code cleanliness. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
