Like I mentioned sometime last year - it's now pretty easy to replace the memleak
detection with other in-kernel mechanisms some of which are in fact even better
than what we have. And considering our mechanisms are totally broken now by the mixup of
wrapped vs nonwrapped allocation/freeing - there's no point in holding to it remaining at all.
The only last bit of useful functionality left, I imagine, is the ability to redirect allocation
to regular kmalloc or to vmalloc based on the allocation size (there's kvfree already for the
freeing part of it).
Other than that the wrappers could go away at any time now, I think.
Bye,
Oleg
