Martin Liu 0b55174ae7 lmkd: Add a margin for watermark when swap free is low am: 95551f816a

Martin Liu 95551f816a lmkd: Add a margin for watermark when swap free is low 
When swap is depleted file cache thrashing might result in allocations
quickly pushing memory below low watermark and kswapd quickly pushing
it back above high watermark. In this situation free memory stays above
high watermark most of the time and lmkd during its periodic wake-ups
has low chance of detecting low memory conditions. Add a 15% margin
for high watermark which would allow lmkd to kill if swap is low,some
memory was reclaimed since the last wakeup and free memory is just
above the high watermark limit.

Ioannis Ilkos 279268a07f Emit swap size in the killed process' statsd atoms 
Changes:
- We are already reading /proc/pid/status to resolve the tgid. While we
are at it, also parse RSS and swap values.
- Use the RSS and swap values for non memcg builds when creating the
statsd outputs
- Given we already read RSS, remove the separate read of /proc/pid/statm
that used to get tasksize.

Suren Baghdasaryan fa667edb56 lmkd: Add lmkd wakeup information into killinfo logs 
Oftentimes while investigating bugreports it's unclear whether lmkd
was active between kills. To provide visibility into lmkd activity
adding the following fields into killinfo reports:
MsSinceEvent - number of msecs since the last PSI/vmpressure event
MsSincePrevWakeup - number of msecs since the previous wakeup
WakeupsSinceEvent - number of wakeups since the last PSI/vmpressure
event
SkippedWakeups - number of wakeups that were skipped due to an
incomplete kill

Suren Baghdasaryan dd8c2c181b lmkd: Set default kill timeout to limit waits for uninterruptible processes 
When lmkd tries to kill a process in uninterruptible sleep state, it may
need to wait for a long time. To prevent this set the default kill timeout
to 100ms which should work for majority of the devices.
