Re: Tracing memory leaks (slabs) in 2.6.9+ kernels?

[Justin Schoeman]

OK - I have the patch working now, but there seems to be a flaw in the 
address reporting. When I look up the reported address in 
/proc/kallsyms, then look in the objdump of the module, the reported 
adress _does_not_ point to a call.

Am I missing something simple here?

I have found some vague references to patches that allow the user to 
dump the caller address for slab allocations, but I cannot find the 
patch itself.

Can anybody please point me in the right direction - either for that 
patch, or any other way to track down leaking slabs?

With the patch applied,
        echo "size-4096 0 0 0" > /proc/slabinfo
walks the objects in the size-4096 slab, printing out the calling address
of whoever allocated that object.
It is for leak detection.
