Subject: [PATCH v2 0/3] Directed kmem charging
Date:   Tue, 20 Feb 2018 19:00:58 -0800
Message-Id: <20180221030101.221206-1-shakeelb@google.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.

  mm: memcg: plumbing memcg for kmalloc allocations
  fs: fsnotify: account fsnotify metadata to kmemcg
