CONFIG_CALL_THUNKS_DEBUG: Enable call thunks and call depth tracking debugging

General informations

The Linux kernel configuration item CONFIG_CALL_THUNKS_DEBUG:

• prompt: Enable call thunks and call depth tracking debugging
• type: bool

• defined in arch/x86/Kconfig

Help text

Enable call/ret counters for imbalance detection and build in a noisy dmesg about callthunks generation and call patching for trouble shooting. The debug prints need to be enabled on the kernel command line with 'debug-callthunks'. Only enable this when you are debugging call thunks as this creates a noticeable runtime overhead. If unsure say N.
