[B.A.T.M.A.N.] [PATCH v3 0/8] batman-adv: Support for complex compat patches

[Sven Eckelmann]

[-- Attachment #1: Type: text/plain, Size: 504 bytes --]

Hi,

here is the updated patchset to get complex compat patches support in batman-
adv. The initial three patches of the last patchset [1] are already part of 
batman-adv.git next. This part is mostly about getting coccinelle/spatch to 
work.

Changes in v3:

 - rebased to get it working on top of current master
 - use __genl_const for batadv_netlink_ops to keep it in ro memory for
   kernel >= 3.13

Kind regards,
	Sven

[B.A.T.M.A.N.] [PATCH v3 1/8] batman-adv: Mark batadv_netlink_ops as const

[Sven Eckelmann]

The genl_ops don't need to be written by anyone and thus can be moved in a
ro memory range.

[B.A.T.M.A.N.] [PATCH v3 2/8] batman-adv: Add support for coccinelle in compat-patches

[Sven Eckelmann]

The kernel and backports already uses spatch from coccinelle for
development and backporting purposes. Thus we can cleanup many current
hacks using semantic patches. These are also a lot less frail than
traditional unified diffs.
