Its filename was mm-rmap-track-whether-the-page-vma-mapped-pgoff-is-anonymous.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: "Lorenzo Stoakes (ARM)" Subject: mm/rmap: track whether the page VMA mapped pgoff is anonymous Date: Thu, 13 Aug 2026 18:32:27 +0100 Update the page_vma_mapped_walk structure to track whether the pgoff being tracked is an anonymous pgoff or not and update the comments to reflect this. This is necessary in order to determine the correct VMA page offset in vma_address_end() when pvmw->nr_pages > 1. Also document that pvmw->pgoff is meaningless for pvmw->nr_pages == 1 and for KSM. Do not set this field where pgoff is not specified. This is laying the groundwork for eventually using anonymous page offsets as the index for all anonymous folios. No functional change intended.
