sf00073670: slub: Store the latest 8 callers of kfree
PPA description
What is the magic number 5 in kmalloc_caches[5] is for fast comparison to the kmalloc-32 object. Because the use-after-free is always happening on the kmalloc-32 object for the Intel's case. We expect to check the callers for analysis when the crash happens.
Store the latest 4 callers of kfree in kmem_cache_node when the free object size is equal to 32 bytes.
