memcg will come in handy in get_scan_count(). It can already be used for
getting swappiness immediately in get_scan_count() instead of passing it
around. The following patches will add more memcg-related values, which
will be used there.

counter. Patches 2-6 make memcg reclaim follow the heuristics used
on global reclaim for handling anon/swap. Patch 7 updates documentation.
Thanks,
Vladimir Davydov (7):
mm: memcontrol: charge swap to cgroup2
mm: vmscan: pass memcg to get_scan_count()
mm: memcontrol: replace

We don't scan anonymous memory if we ran out of swap, neither should we
do it in case memcg swap limit is hit, because swap out is impossible
anyway.

The following patches will add more functions to the memcg section of
include/linux/swap.h. Some of them will need values defined below the
current location of the section. So let's move the section to the end of
the file. No functional changes intended.

tcp_memcontrol.c only contains legacy memory.tcp.kmem.* file definitions
and mem_cgroup->tcp_mem init/destroy stuff. This doesn't belong to
network subsys. Let's move it to memcontrol.c. This also allows us to
reuse generic code for handling legacy memcg files.
