Subject: memcg: enable accounting for VLAN group array
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a89893dd7b08fa85bcf643ca742ab388e001c08e;p=linux.git

memcg: enable accounting for VLAN group array

vlan array consume up to 8 pages of memory per net device.

It makes sense to account for them to restrict the host's memory
consumption from inside the memcg-limited container.
