Subject: Finding out whether memory was allocated with kmalloc or vmalloc

Hi,

given a pointer p, is there an easy and platform independent way to find out,
whether the memory location that p points to was allocated with kmalloc or
vmalloc?

Thanks

Vmalloc'ed memory has a virtual address VMALLOC_START <= x < VMALLOC_END.
