Merge branch 'genetlink'
Johannes Berg says: ==================== genetlink: reduce ops size and complexity (v2) As before - reduce the complexity and data/code size of genetlink ops by making them an array rather than a linked list. Most users already use an array thanks to genl_register_family_with_ops(), so convert the remaining ones allowing us to get rid of the list head in each op. Also make them const, this just makes sense at that point and the security people like making function pointers const as well :-) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
