The percpu part looks fine to me but I don't know how kmemleak works
to judge whether the kmemleak part is okay or not. This just avoids
false positives from slab and would still require bumping up the early
log memory as # of cpus increases, right?
For percpu part,
Acked-by: Tejun Heo <tj@kernel.org>
How do you want to route this? If kmemleak patches get routed through
-mm, please feel free to send it to Andrew with Acked-by's added.
Thank you.
