# unmount-watcher.stp
# Watches for filesystem unmounts and prints additional information about them.
# Authored by Robb Manes <[email protected]>

# Execute by running:
#  stap unmount-watcher.stp > unmount-watcher.out

# In containerized environments, the unmounting process may belong to a different process namespace, so it's useful to print the
# entire tree to determine where it came from.
# This is borrowed from https://sourceware.org/systemtap/examples/network/connect_stat.stp
