Hi Johannes,
I tested with your patches but situation is still mostly the same.
Spend some time for debugging and found that the problem is squashfs

Hopefully I was able to rebase the patch on top v4.9.26 (latest
supported version by us right now)
and test a bit.
The overall idea definitely looks promising, although I have one

In our devices under low memory conditions we often get into a trashing
state when system spends most of the time re-reading pages of .text
