Now there are two indicators of socket memory pressure sit inside
struct mem_cgroup, socket_pressure and tcpmem_pressure.
When in legacy mode aka. cgroupv1, the socket memory is charged
into a separate counter memcg->tcpmem rather than ->memory, so
the reclaim pressure of the memcg has nothing to do with socket's
pressure at all. While for default mode, the ->tcpmem is simply
not used.
So {socket,tcpmem}_pressure are only used in default/legacy mode
respectively. This patch fixes the pieces of code that make mixed
use of both.
