Hi,
this is my attempt to backport Johannes' 73f576c04b94 ("mm: memcontrol:
fix cgroup creation failure after many small jobs") to 4.4 based stable
kernel. The backport is not straightforward and there are 2 follow up
fixes on top of this commit. I would like to integrate these to our SLES
based kernel and believe other users might benefit from the backport as
well. All 3 patches are in the Linus tree already.I would really appreciate if Johannes could double check after me before this gets into the stable tree but my testing didn't reveal anything unexpected. Thanks!
