net: add uevent socket member
This commit adds struct uevent_sock to struct net. Since struct uevent_sock records the position of the uevent socket in the uevent socket list we can trivially remove it from the uevent socket list during cleanup. This speeds up the old removal codepath. Note, list_del() will hit __list_del_entry_valid() in its call chain which will validate that the element is a member of the list. If it isn't it will take care that the list is not modified. Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
