Subject: net: af_netlink should update its inuse counter
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c1fd3b9455a977057f73534324d4e07a3d9fe502;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net: af_netlink should update its inuse counter

In order to have relevant information for NETLINK protocol, in
/proc/net/protocols, we should use sock_prot_inuse_add() to
update a (percpu and pernamespace) counter of inuse sockets.
