+# Test overview:
+# Check that non-privileged users can also clean up stale linkto files
+#
+# 1. Use the current parallel-readdir behaviour of changing the DHT child subvols
+# in the graph to generate stale linkto files
+# 2. Access the file with the stale linkto file as a non-root user
+# 3. This should now succeed (returned EIO before commit 3fb1df7870e03c9de)
