[RFC PATCH 0/3] Directed kmem charging

From: Shakeel Butt
Date: Tue Feb 13 2018 - 21:58:07 EST


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.
