Subject: [PATCH 0/2] ipv4: Namespaceify two sysctls related with mtu

From: xu xin <xu.xin16@....com.cn>

The following patch series enables the min_pmtu and mtu_expires to
be visible and configurable per net namespace. Different namespace
application might have different requirements on the setting of
min_pmtu and mtu_expires.

If these two patches are applied, inside a net namespace we create,
we can see two more sysctls under /proc/sys/net/ipv4/route:
1. min_pmtu
2. mtu_expires

where min_pmtu and mtu_expires are configurable.

xu xin (2):
namespaceify-min-pmtu
Namespaceify pmtu_expires

xu xin (2):
  Namespaceify min_pmtu sysctl
  Namespaceify mtu_expires sysctl
