Subject: [PATCH 3.16 143/254] sctp: Replace use of sockets_allocated with
 specified macro.

3.16.55-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Tonghao Zhang <xiangxia.m.yue@...il.com>

commit 8cb38a602478e9f806571f6920b0a3298aabf042 upstream.

The patch(180d8cd942ce) replaces all uses of struct sock fields'
memory_pressure, memory_allocated, sockets_allocated, and sysctl_mem
to accessor macros. But the sockets_allocated field of sctp sock is
not replaced at all. Then replace it now for unifying the code.

Fixes: 180d8cd942ce ("foundations of per-cgroup memory pressure controlling.")
