Much smaller logs so I'm attaching them.
Just to clarify. You have added the trace_printk for
try_to_release_page, right? (after fixing it of course). If yes
there is
no single mention of that path failing which would support Joonsoo's
theory... Could you try with his patch?
And then it would be great if you could test with the current
linux-next
tree. Vlastimil has done some changes which might help. But even if
they
don't then it would be better to add more changes on top of them.
Results with 4.8.0-rc2 are attached. OOM happened rather quickly.
4.8.0-rc2 is not "linux-next". What Michal meant is the linux-next git
(there's no tarball on kernel.org for it):
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
Hmm. I added linux-next git, fetched it etc but apparently I didn't
check out the right branch. Do you want next-20160817?
