Subject: [PATCH mm v3 2/9] memcg: enable accounting for kernfs nodes
Date: Mon, 30 May 2022 14:26:00 +0300	[thread overview]
Message-ID: <aeb2adf8-04ad-2f7a-dc03-c1bf0f71450a@openvz.org> (raw)
In-Reply-To: <cover.1653899364.git.vvs@openvz.org>

kernfs nodes are quite small kernel objects, however there are few
scenarios where it consumes significant piece of all allocated memory:

1) creating a new netdevice allocates ~50Kb of memory, where ~10Kb
   was allocated for 80+ kernfs nodes.

2) cgroupv2 mkdir allocates ~60Kb of memory, ~10Kb of them are kernfs
   structures.

3) Shakeel Butt reports that Google has workloads which create 100s
   of subcontainers and they have observed high system overhead
   without memcg accounting of kernfs.

Usually new kernfs node creates few other objects:

Allocs  Alloc   Allocation
number  size
--------------------------------------------
1   +  128      (__kernfs_new_node+0x4d)	kernfs node
1   +   88      (__kernfs_iattrs+0x57)		kernfs iattrs
1   +   96      (simple_xattr_alloc+0x28)	simple_xattr, can grow over 4Kb
1       32      (simple_xattr_set+0x59)
1       8       (__kernfs_new_node+0x30)

'+' -- to be accounted

This patch enables accounting for kernfs nodes slab cache.
