Quite often I might put introductory paragraphs before that, so I prefer to begin the paragraph that states a fix with that verb. There may also be auxiliary changes associated with it that aren't directly fixes but need to be made because of the fix change. > * Is freeing and releasing an item a duplicate operation anyhow? You're missing the point. afs_put_sysnames() does release the things the object points to (ie. the content), but not the object itself. > >> Will it matter to mention the size of the data structure "afs_sysnames"? > > > > Why is it necessary to do so? > > I suggest to express the impact of the missed function call "kfree". I would hope that anyone reading the patch could work the impact out for themselves. Just specifying the size of a struct isn't all that useful - it may be wildly variable by arch (eg. 32/64) and config option (eg. lockdep) anyway. Add to that rounding and packing details from the memory subsys, along with the pinning effect of something you can't get rid of. Of more use would be specifying the frequency or likelyhood of such a leak but unless it's especially high, it's probably not worth mentioning. David
