No, because unlink and rename are NO modifications to the file (represented
by the i-node) but modifications to the directory. The KErnel has the file
open (pointed to it by inode) and any modifications to the filename are
completely uninteresting to it. Thats why you can delete (unlink) a file and
it is still accessable until the last close (refcnt=0).
