| 16 | Enable reference count tracking for DPLL devices and pins. |
| 17 | This helps debugging reference leaks and use-after-free bugs |
| 18 | by recording stack traces for each get/put operation. |
| 19 | |
| 20 | The tracking information is exposed via debugfs at: |
| 21 | /sys/kernel/debug/ref_tracker/dpll_device_* |
| 22 | /sys/kernel/debug/ref_tracker/dpll_pin_* |
| 23 | |
| 24 | If unsure, say N. |
