The patch itself now looks fine to me. The log entry is inadequate. It needs to mention each file and function touched and say what was done there. "Update caller." is sufficient text for a function to which the only change was trivial argument reordering or whatnot. But in most of these cases, each caller dropped a stat* call as well and so it needs to say "Pass it -1 instead of calling stat64." or suchlike.
Thanks, Roland
