The following operation produces kernel messages mentioned in subject:
vvv:/usr/local/src# tar xfz mc-4.1.8.tar.gz
vvv:/usr/local/src# rm -r mc-4.1.8
ext2_rmdir: d_count=112, pruning
ext2_rmdir: d_count=20, pruning
ext2_rmdir: d_count=10, pruning
ext2_rmdir: d_count=17, pruning

ext2_rmdir: d_count=34, pruning
I.e., immediately after untarring a big archive, I recursively delete the tree.
This is 100% reproducible.
