[PATCH] net: sctp should update its inuse counter

[PATCH] net: sctp should update its inuse counter

[Eric Dumazet]

[-- Attachment #1: Type: text/plain, Size: 352 bytes --]

This patch is a preparation to namespace conversion of /proc/net/protocols

In order to have relevant information for SCTP protocols, we should use
sock_prot_inuse_add() to update a (percpu and pernamespace) counter of
inuse sockets.
