Description of problem: rmdir of a non-empty directory, that has a whiteout, will remove successfully. Version-Release number of selected component (if applicable): 4.0.2-300.fc22.x86_64 How reproducible: consistent Steps to Reproduce: ``` base=$(mktemp -d) echo ${base} ## make an overlay fs setup mkdir -p ${base}/{upper,work,merged,mnt,lower} ## make an empty directory in the base layer mkdir ${base}/lower/empty ## mount the base layer sudo mount \ -t overlay \ -o rw,lowerdir=${base}/lower/,workdir=${base}/work/,upperdir=${base}/upper/ \ ${base}/merged/ ${base}/mnt/ ## create a whiteout rmdir ${base}/mnt/empty ## add the dir back (on top of the whiteout) mkdir -p ${base}/mnt/empty touch ${base}/mnt/empty/file.txt ## now rm the non-empty directory rmdir ${base}/mnt/empty && echo "bug here!" ## cleanup and info sudo umount ${base}/mnt sudo find ${base} ``` Actual results: rmdir removes the non-empty directory and returns success Expected results: failure to rmdir the non-empty directory Additional info: Found in a docker issue report - https://github.com/docker/docker/issues/13108
