[PATCH v4 0/2] tools/mm/page_owner_sort: split filter cleanup and allocation fix

[Yichong Chen]

Hi,

Split the v3 change into two patches as suggested by Vishal.

Patch 1 renames is_need() to filter_record() and makes the filter path
return explicit results. Patch 2 fixes the per-record allocation leaks.

Changes in v4:
- Split the filter_record() cleanup into a separate patch.
- Mention the is_need() to filter_record() rename in the commit log.
- Add Reviewed-by from Vishal.

Changes in v3:
- Keep the free in add_list(), since incomplete records are not included
  in list_size and cannot be reached by the common cleanup path.
- Return explicit error, skip, and match results from filter_record() to
  handle a NULL return from get_comm().

Changes in v2:
- Wrap commit message lines to approximately 75 columns.
- Use "Yichong Chen" as the author name.

Yichong Chen (2):
  tools/mm/page_owner_sort: return explicit filter results
  tools/mm/page_owner_sort: free per-record allocations

Thanks.

We're now at -rc1 (almost), so expect people to start paying more
attention.  Please plan on resending this series next week.

Please try to sort out the message threading - sending these as
separate emails seems to have fooled AI review.

AI review might have found several issues in here, all of them
pre-existing.

Ye Liu and Zhen Ni (both cc'ed) have been working on page_owner
recently, so please let's keep them informed - they may be interested
in your changes and in the possible issues which Sashiko has
identified.
