Let me clarify.

1. I sent [1] (9 patches)

2. You queued the 9 patches

E.g., in "mmotm 2022-02-15-20-22 uploaded"

* mm-optimize-do_wp_page-for-exclusive-pages-in-the-swapcache.patch
* mm-optimize-do_wp_page-for-fresh-pages-in-local-lru-pagevecs.patch
* mm-slightly-clarify-ksm-logic-in-do_swap_page.patch
* mm-streamline-cow-logic-in-do_swap_page.patch
* mm-huge_memory-streamline-cow-logic-in-do_huge_pmd_wp_page.patch
* mm-khugepaged-remove-reuse_swap_page-usage.patch
* mm-swapfile-remove-stale-reuse_swap_page.patch
* mm-huge_memory-remove-stale-page_trans_huge_mapcount.patch
* mm-huge_memory-remove-stale-locking-logic-from-__split_huge_pmd.patch

3. The last patch in the series was dropped. What remains are 8 patches.

E.g., in "mmotm 2022-02-24-22-38 uploaded"

* mm-optimize-do_wp_page-for-exclusive-pages-in-the-swapcache.patch
* mm-optimize-do_wp_page-for-fresh-pages-in-local-lru-pagevecs.patch
* mm-slightly-clarify-ksm-logic-in-do_swap_page.patch
* mm-streamline-cow-logic-in-do_swap_page.patch
* mm-huge_memory-streamline-cow-logic-in-do_huge_pmd_wp_page.patch
* mm-khugepaged-remove-reuse_swap_page-usage.patch
* mm-swapfile-remove-stale-reuse_swap_page.patch
* mm-huge_memory-remove-stale-page_trans_huge_mapcount.patch

4. Yang Shi sent his patch (the one we're replying to)

5. You picked his patch and dropped it again due to [2]


I'm wondering why 3 happened and why
https://www.ozlabs.org/~akpm/mmotm/series contains:


mm-optimize-do_wp_page-for-exclusive-pages-in-the-swapcache.patch
mm-optimize-do_wp_page-for-fresh-pages-in-local-lru-pagevecs.patch
