lmkd: Allow lmkd to kill perceptible apps during heavy thrashing
...
Occasionally a system can get into heavy file cache thrashing situation
and become unresponsive. In these situations we observe lmkd wakeups,
however it does not kill because all non-perceptible apps are already
killed and the system manages to reclaim enough memory to stay above
min watermark.
Add ro.lmk.thrashing_limit_critical property which when breached will
allow lmkd to kill perceptible apps. The property represents the
percentage of refaulted workingset pages as a fraction of overall file
cache size. By default it is disabled.

lmkd: choose the heaviest task when killing perceptible processes
...
When killing a task at or lower than oom_score_adj PERCEPTIBLE_APP_ADJ
choose the heaviest task among the ones at that level to try minimizing
the number of required kills. Because killing a perceptible app will
affect user experience anyway, it makes sense to choose the one that
will release the most memory and therefore no more kills might be
necessary.
