[PATCH net-next 0/2] Converting pernet_operations (part #10)

[PATCH net-next 0/2] Converting pernet_operations (part #10)

[Kirill Tkhai]

Hi,

this series continues to review and to convert pernet_operations
to make them possible to be executed in parallel for several
net namespaces at the same time. There are two ops similar
to already converted ip4_frags_ops.

This requires a560002437d3 "net: Fix hlist corruptions
in inet_evict_bucket()", which is currently in net.git.

It seems to be the finial convertion series.

Thanks,
Kirill

[PATCH net-next 1/2] net: Convert lowpan_frags_ops

[Kirill Tkhai]

These pernet_operations register and unregister sysctl.
Also, there is inet_frags_exit_net() called in exit method,
which has to be safe after a560002437d3 "net: Fix hlist
corruptions in inet_evict_bucket()".
