[Antonio Quartulli]

here is our second patchset intended for net-next/linux-3.9.
In this batch you have some struct refactoring and a great kernel doc
improvement by Marek Lindner. In patch 10/13 you have the random32() function
renaming proposed by Akinobu Mita.

In 11/13 instead you have a behavioural change brought by Simon Wunderlich which
is modifying the way a batman-adv virtual interface is unregistered in order to
prevent a possible deadlock involving rntl_lock and s_active. We have
already been discussing about this problem and its possible solution on the
netdev mailing list.
The rest is just clean up work.

Please pull or let me know if there is any problem.

Thanks a lot,
	Antonio

[B.A.T.M.A.N.] [PATCH 01/13] batman-adv: a delayed_work has to be initialised once

[Antonio Quartulli]

A delayed_work struct does not need to be initialized each
every time before being enqueued. Therefore the
INIT_DELAYED_WORK() macro should be used during the
initialization process only.

[B.A.T.M.A.N.] [PATCH 11/13] batman-adv: postpone sysfs removal when unregistering

[Antonio Quartulli]

From: Simon Wunderlich <simon.wunderlich@s2003.tu-chemnitz.de>

When processing the unregister notify for a hard interface, removing
the sysfs files may lead to a circular deadlock (rtnl mutex <->
s_active).

To overcome this problem, postpone the sysfs removal in a worker.
