Inspired by PSI features, vmpressure inotifier function should
also be configured to decide whether it is used, because it is an
independent feature which notifies the user of memory pressure.

It is also used by the networking stack to check memory pressure. See
mem_cgroup_under_socket_pressure().

 Thanks for your replly, mem_cgroup_under_socket_pressure does use vmpressue,
 I'll check it.
