Its filename was mm-add-vma_iter_nextprev_range-to-vma-iterator.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: "Liam R. Howlett" Subject: mm: add vma_iter_{next,prev}_range() to vma iterator Date: Thu, 18 May 2023 10:55:43 -0400 Add functionality to the VMA iterator to advance and retreat one offset within the maple tree, regardless of the value contained. This can lead to less re-walking to find an area of interest, especially when there is nothing in that offset.
