# 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)
