SLUB (The unqueued slab allocator) is a memory allocator used by the Linux kernel. It is used to allocate chunks of memory for kernel objects and data structures. The "Enable SLUB debugging support" kernel configuration option provides additional debugging features for the SLUB allocator.
Enabling this option adds extra checks and validation to the SLUB allocator's code to detect and report various issues such as memory leaks, buffer overflows, and other memory-related bugs. This can help developers identify and fix issues in the kernel code more easily.
However, enabling SLUB debugging support also adds some overhead to the kernel's memory allocation process, which can impact performance. Therefore, it is usually recommended to enable this option only when debugging kernel code.
