missed this post. thx for pointing out.

agree. now my own patch is to check errno, if ENOENT, then set to
VANISHED instead of PARTIAL. because i really want to tell if a file is
disappeared (by unlink which later inotify event will be handled) from a
file is fail to transfer because of io error or something else.
