Passing in a reply task runner seems odd. I'd expect the caller to expect to be
called back on the same thread, and pass in a callback that proxies to the other
thread if necessary so this utility is ignorant of that complexity.

(Seems like that should be a pattern factored out somewhere.)

Done.

   static int64_t CallGetAmountOfFreeDiskSpace(
       GetVolumeInfoFn get_vol_info_fn,
       const base::FilePath& profile_path);
