It helps. Thank you, Joerg!

The .kde/cache-ibm/socket-ibm/0266584877 above are directories.
It's weird that dirs would have their own mappings in ext2. In
particular this bug is triggered because the dir mapping page has
PAGECACHE_TAG_DIRTY set and PG_dirty cleared, staying in an
inconsistent state.
