net: wrap sock->sk_cgrp_prioidx and ->sk_classid inside a struct
Introduce sock->sk_cgrp_data which is a struct sock_cgroup_data.
->sk_cgroup_prioidx and ->sk_classid are moved into it. The struct
and its accessors are defined in cgroup-defs.h. This is to prepare
for overloading the fields with a cgroup pointer.
This patch mostly performs equivalent conversions but the followings
are noteworthy.
* Equality test before updating classid is removed from
sock_update_classid(). This shouldn't make any noticeable
difference and a similar test will be implemented on the helper side
later.
* sock_update_netprioidx() now takes struct sock_cgroup_data and can
be moved to netprio_cgroup.h without causing include dependency
loop. Moved.
* The dummy version of sock_update_netprioidx() converted to a static
inline function while at it.
