I also thought another proposed flag was to determine whether mtime (and maybe ctime) is changed when doing prealloc/dealloc space? Default should probably be to change mtime/ctime, and have FA_FL_NO_MTIME. Someone else should decide if we want to allow changing the file w/o changing ctime, if that is required even though the file is not visibly changing. Maybe the ctime update should be implicit if the size or mtime are changing?
