This patchset introduces memcg variant memory allocation functions. The caller can explicitly pass the memcg to charge for kmem allocations. Currently the kernel, for __GFP_ACCOUNT memory allocation requests, extract the memcg of the current task to charge for the kmem allocation. This patch series introduces kmem allocation functions where the caller can pass the pointer to the remote memcg. The remote memcg will be charged for the allocation instead of the memcg of the caller. However the caller must have a reference to the remote memcg. Fixed the build for SLOB in v2.
