| |
From: Pekka Enberg <penberg@cs.helsinki.fi>
The kernel now has kmemleak and kmemtrace so there's no reason to keep this ugly s390 hack around. I am not sure how it's supposed to work on SMP anyway as it uses a global variable to temporarily store the return value of all kmalloc() calls:
void *b;
#define kmalloc(x...) (PRINT_INFO(" kmalloc %p\n",b=kmalloc(x)),b)
