OK, so the allocation couldn't make a forward progress for more than
10s. You do not seem to have many file pages on the LRU lists left
and so you only have anonymous memory as reclaimable. Slab doesn't
have many pages either. Everything together makes it 1886MB out of 2GB.
~50MB is free so this means ~70MB is in unaccounted memory (50MB is
reserved) which looks reasonably and I wouldn't suspect any kernel
memory leak

pretty much the same picture. Both inactive and active anonymous LRU
lists have grown a bit which means that the anonymous memory pressure
continues. This is the same process stalling but it is a different
alloation request.

and again the picture is similar. inactive anonymous list shrunk by ~700
pages but the active list has grown by ~600 pages. This suggests we are
seeing activated pages on the inactive list and promote them so the
anonymous memory is actively used.

And again the anonymous memory pressure grows. So I would suspect some
userspace application went off the hook and started consuming a lot of
anonymous memory which gets you to a trashing stage when basically
nothing can move on much without swap out. The page cache is at its
minimum and I suspect that most binaries would have to be read from disk
and you reached the point of trashing. I am afraid we are not really
great at handling these situations from the kernel well. Killing the
memory hog would be probably the most sane thing to do.

I don't know what "DOM Worker" process is. But guessing from that there is
"firefox-esr" process, "DOM Worker" is a process related to HTML5 Web Workers API.
Since web browser processes can heavily consume memory depending on the content
loaded (or memory leak of plugins), it is possible that you are overstressing
the system.
"DMA32 free:" is below "DMA32 min:" which I think means that the OOM killer
would have been triggerred immediately if there is no swap.
I guess there were other processes which stalled less than 10 seconds. Maybe
processes stalling at doing swap I/O exist, but we can't know them because
warn_alloc() threshold is not configurable and __GFP_NOWARN allocations are
not reported by warn_alloc(). Too bad.
If you can rebuild your kernel, calling dump_tasks() in mm/oom_kill.c when
you hit warn_alloc() warnings might help. If you cannot, SysRq-f will be
handy to check.
If you still suspect that this is a kernel problem, you can try older kernels
for comparison purpose which you think everything was working well, though
warn_alloc() was added in Linux 4.9.

I do not really see how this would help much. If anything watching for
/proc/vmstat counters would tell us much more.

Under memory pressure, read()/write() syscalls might involve significant delay
(including reading from /sys/kernel/debug/tracing/trace_pipe and writing to
a log file). Unless all problems are contained in a cgroup (which means that
administrators can diagnose from outside of that cgroup), it is silly to try to
read memory related information of a stalling system using userspace interface.
Therefore, automatic printk() is helpful than trying to start "cat /proc/vmstat"
from a shell. I wish there is a kernel function which does
"cat /proc/some_file" and/or "cat /sys/kernel/debug/tracing/trace_pipe" and
sends the output to printk() so that such actions will not involve significant
delay under memory pressure.

My laptop became almost totally un responsive today. I was able to
switch VTs but not log in and had to power cycle to regain control. I
don't understand what this means. Any ideas?
