Note that shared memory allocations were up to about 20GB when taking this
data, according to the page owner data most of that was allocated by i915.
Some minutes after above snapshot I'm seeing:
# cat /sys/kernel/debug/dri/0/i915_gem_objects
1224 shrinkable [0 free] objects, 716410880 bytes

stolen-system: total:0x0000000004000000, available:0x0000000004000000 bytes
Shared memory usage hasn't really dropped, though.
