Its filename was mm-pgtable-correct-the-wrong-comment-about-ptdesc-__page_flags.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Qi Zheng Subject: mm: pgtable: correct the wrong comment about ptdesc->__page_flags Date: Mon, 4 Mar 2024 19:07:18 +0800 Patch series "minor fixes and supplement for ptdesc". In this series, the [PATCH 1/3] and [PATCH 2/3] are fixes for some issues discovered during code inspection. The [PATCH 3/3] is a supplement to ptdesc conversion in s390, I don't know why this is not done in the commit 6326c26c1514 ("s390: convert various pgalloc functions to use ptdescs"), maybe I missed something. And since I don't have an s390 environment, I hope kernel test robot can help compile and test, and this is why I did not fold [PATCH 2/3] and [PATCH 3/3] into one patch. This patch (of 3): The commit 32cc0b7c9d50 ("powerpc: add pte_free_defer() for pgtables sharing page") introduced the use of PageActive flag to page table fragments tracking, so the ptdesc->__page_flags is not unused, so correct the wrong comment.
