Subject: [PATCH v4 0/4] page_owner: Fix refcount imbalance and print fixup
This series consists of a refactoring/correctness of updating the metadata
of tail pages, a couple of fixups for the refcounting part and a fixup for
the stack_start() function.
>From this series on, instead of counting the stacks, we count the outstanding
nr_base_pages each stack has, which gives us a much better memory overview.
The other fixup is for the migration part.
A more detailed explanation can be found in the changelog of the respective
patches.
v3 -> v4:
- Fix some typos remarked by Vlastimil
- Add Reviewed-by tag from Vlastimil and Tested-by tag from Alexandre Ghiti
(closed a syzbot report for RISC)
