Subject: nfsdcltrack: skip "." and ".." when trying to clean out legacy recdir
X-Git-Tag: debian/1%1.2.8-1~11^2^2~51

nfsdcltrack: skip "." and ".." when trying to clean out legacy recdir

readdir picks up these two entries as "normal" dentries, but rmdir'ing
them won't work (and we wouldn't want to remove them anyway).
