DPLL reference count tracking

configname: CONFIG_DPLL_REFCNT_TRACKER

Linux Kernel Configuration
└─>Device Drivers

└─>DPLL reference count tracking
In linux kernel since version 6.19.5 (release Date: 2026-02-27)
Enable reference count tracking for DPLL devices and pins.
This helps debugging reference leaks and use-after-free bugs
by recording stack traces for each get/put operation.

The tracking information is exposed via debugfs at:
/sys/kernel/debug/ref_tracker/dpll_device_*
/sys/kernel/debug/ref_tracker/dpll_pin_*

If unsure, say N.
