hi all: I found in alloc_bootmem_bdata, kmem_cache_alloc, kmalloc, vmalloc, they will call kmemleak_alloc.

Would anyone know why we have to do so for calling kmemleak_alloc at different places?

AFAIK this is used for accounting allocated memory in order to easily track down memory leaks. It is implemented by the kmemleak detector. thanks, Daniel.
