2017-06-20percpu: expose statistics about percpu memory via debugfsDennis Zhou1-0/+222
There is limited visibility into the use of percpu memory leaving us unable to reason about correctness of parameters and overall use of percpu memory. These counters and statistics aim to help understand basic statistics about percpu memory such as number of allocations over the lifetime, allocation sizes, and fragmentation.
