Subject: [VLAN]: Avoid a 4-order allocation.
X-Git-Tag: v2.6.21-rc3~101^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5c15bdec5c38f4ccf73ef2585fc80a6164de9554;p=pandora-kernel.git

[VLAN]: Avoid a 4-order allocation.

This patch splits the vlan_group struct into a multi-allocated struct. On
x86_64, the size of the original struct is a little more than 32KB, causing
a 4-order allocation, which is prune to problems caused by buddy-system
external fragmentation conditions.

I couldn't just use vmalloc() because vfree() cannot be called in the
softirq context of the RCU callback.
