Sorry for the delay in replying. I had to give an extended run under
kernel 4.2.0-rc6 to obtain comparative results. Both kernels' config
files are attached.
The applications running are the same both times, mainly iceweasel
38.1.0esr-3 and chromium 44.0.2403.107-1.
With the rc7+ kernel but not the rc6 kernel, chromium eventually gets
into a state of consuming lots of swap.
I was able to capture the output requested when running a 4.2.0-rc7+
kernel (Linus' git head as of around 05:00 UTC 19 August 2015) just
before swap was exhausted, forcing me to do a control-alt-delete
shutdown and waiting ages. The kernel config for the rc7+ is attached
The comparison good kernel is from Debian:
Linux am64 4.2.0-rc6-amd64 #1 SMP Debian 4.2~rc6-1~exp1 (2015-08-12)
x86_64 GNU/Linux
Output of the script quoted above for the rc7+ kernel is:
