-11. Memory Pressure
-
-The pressure level notifications can be used to monitor the memory
-allocation cost; based on the pressure, applications can implement
-different strategies of managing their memory resources. The pressure
-levels are defined as following:
-
-The "low" level means that the system is reclaiming memory for new
-allocations. Monitoring this reclaiming activity might be useful for
-maintaining cache level. Upon notification, the program (typically
-"Activity Manager") might analyze vmstat and act in advance (i.e.
-prematurely shutdown unimportant services).
-
-The "medium" level means that the system is experiencing medium memory
-pressure, the system might be making swap, paging out active file caches,
-etc. Upon this event applications may decide to further analyze
-vmstat/zoneinfo/memcg or internal memory usage statistics and free any
-resources that can be easily reconstructed or re-read from a disk.
-
-The "critical" level means that the system is actively thrashing, it is
-about to out of memory (OOM) or even the in-kernel OOM killer is on its
-way to trigger. Applications should do whatever they can to help the
-system. It might be too late to consult with vmstat or any other
-statistics, so it's advisable to take an immediate action.
-
-The events are propagated upward until the event is handled, i.e. the
-events are not pass-through. Here is what this means: for example you have
-three cgroups: A->B->C. Now you set up an event listener on cgroups A, B
-and C, and suppose group C experiences some pressure. In this situation,
-only group C will receive the notification, i.e. groups A and B will not
-receive it. This is done to avoid excessive "broadcasting" of messages,
-which disturbs the system and which is especially bad if we are low on
-memory or thrashing. So, organize the cgroups wisely, or propagate the
-events manually (or, ask us to implement the pass-through events,
-explaining why would you need them.)
-
-The file memory.pressure_level is only used to setup an eventfd. To
-register a notification, an application must:
-
-- create an eventfd using eventfd(2);
-- open memory.pressure_level;
-- write string like "<event_fd> <fd of memory.pressure_level> <level>"
-  to cgroup.event_control.
-
-Application will be notified through eventfd when memory pressure is at
-the specific level (or higher). Read/write operations to
-memory.pressure_level are no implemented.
-
-Test:
-
-   Here is a small script example that makes a new cgroup, sets up a
-   memory limit, sets up a notification in the cgroup and then makes child
-   cgroup experience a critical pressure:
-
-   # cd /sys/fs/cgroup/memory/
-   # mkdir foo
-   # cd foo
-   # cgroup_event_listener memory.pressure_level low &
-   # echo 8000000 > memory.limit_in_bytes
-   # echo 8000000 > memory.memsw.limit_in_bytes
-   # echo $$ > tasks
-   # dd if=/dev/zero | read x
-
-   (Expect a bunch of notifications, and eventually, the oom-killer will
-   trigger.)

-	Part 6 - Disabling clock gating of unused clocks
-
-Sometimes during development it can be useful to be able to bypass the
