netlink_kernel_create() always returns NULL
2011/2/22 YANG <email@example.com>:
> My code fragment is below:
> "nl_sk = netlink_kernel_create(16, 0, nl_data_ready, THIS_MODULE);"
> It can be "make" and "insmod" correctly. But error mesage is printed into
> log. It indicates the netlink_kernel_create() returns NULL.
> Once I change the firt parameter to another(<32 && >16), system crash when I
> execute insmod.
> Is the protocol ID occupied? Why can't use another and how to define a new
> ID? I have tried to update net_link.h but fail also.
