Subject: [PATCH V2 0/2] Introduce panic function when slub leaks

Hi all,

A method to detect slub leaks by monitoring its usage in real time
on the page allocation path of the slub. When the slub occupancy
exceeds the user-set value, it is considered that the slub is leaking
at this time, and a panic operation will be triggered immediately.

Changes in v2:
- Fix error that unterminated conditional directive
- Avoid using #ifdef when referencing .h in .c files

Changes in v1:
- Add panic function when slub leaks
- Add parameter description for slub_leak_panic function
