Ooops, there was a formatting error in the cover letter, my apologies.

Here is a fixed version:

Subject: [PATCH v2 0/5] mm: memcg: merge page_counter trees

This patchset reorganizes page_counter structures which helps to make
memory cgroup and hugetlb cgroup structures smaller (10%-35% depending
on the kernel configuration) and more cache-effective. It also eliminates
useless tracking of protected memory usage when it's not needed.

v2:
  - two page_counter structures per hugetlb cgroup instead of one
  - rebased to the current mm branch
  - many minor fixes and improvements
v1:
  https://lore.kernel.org/lkml/20240503201835.2969707-1-roman.gushchin@linux.dev/T/#m77151ed83451a49132e29ef13d55e08b95ac867f

Hi Roman, what is the base of this series? Is it linus tree or
mm-unstable?

Hi Shakeel!

It's a today's snapshot of mm-unstable (d8492982371a). It had some
conflicts with the recent memory.peak series, which I resolved today.

The whole series can be found here:
https://github.com/rgushchin/linux/tree/page_counters.2 .

Thanks!

Yes, the [0/n] is pretty screwy and I'm hitting some rejects against
the latest patchpile.  Can we please have a v2 against latest
mm-unstable, which I expect to push out a few hours from now?  Thanks.
