I’m troubleshooting some Linux kernel code, and it would be nice to know where the memory pointer allocation originated.

Question: Are there Linux kernel macros available like ADDR_IS_STACK_ADDR(ptr) or ADDR_IS_HEAP_ADDR(ptr) so I can check where an addr might have come from? If so, please point me in the right direction

In my case I just want to know if it is from a stack variable passed by reference… but it might be nice to know if there are macros to check:

• is the address from the stack?
• is the address from the kmalloc?
• is the address from the vmalloc?
• from .text , like a function pointer?
• other classifications?
