The fix is fairly simple. We need to tell kmemleak to ignore PUD
allocations and never report them as leaks. We can also tell it not to
scan the PGD, because it will never find pointers in there. However it
will still notice if we allocate a PGD and then leak it.

Thanks.

No problem. I forgot to add, that it=E2=80=99d be great, if you tagged th=

is

for the stable series too.

Sorry I didn't see this before I applied, so it's not tagged for stable.

We can request a backport though, what stable version(s) are you
running?

cheers
