This integration requires read access to files under `/sys/kernel/debug/extfrag`, which are accessible

debugfs. `CAP_DAC_READ_SEARCH` is added automatically during installation. This capability allows bypassing
file read permission checks and directory read and execute permission checks. If file capabilities are not
