Note, there is not a 1 to 1 with keys and places that need to be patched.
Doing the following objdump:
objdump -dr vmlinux | grep 'jmpq.*<trace_kmalloc' | wc -l 375
That's 375 instances of kmalloc tracepoints[*] and one key. How do you handle this?

[*] this should be fixed, we probably should find a way to move the tracepoint into the kmalloc functions that are not inlined.
