For CONFIG_BUILD_KERNEL using the sched/task/task_exithook implementation will just not work. It calls user code with kernel privileges which is a bit of a security issue.

* Name: __cxa_atexit
|
|
*
|
|
* Description:
|
|
* __cxa_atexit() registers a destructor function to be called by exit().
|
|
* On a call to exit(), the registered functions should be called with
|
|
* the single argument 'arg'. Destructor functions shall always be
|
|
* called in the reverse order to their registration (i.e. the most
|
|
* recently registered function shall be called first),
|
|
*
|
|
* If shared libraries were supported, the callbacks should be invoked
|
|
* when the shared library is unloaded as well.
|

* Reference:
|
|
* Linux base
