Its filename was mm-pass-through-vma-iterator-to-__vma_adjust.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: pass through vma iterator to __vma_adjust() Date: Fri, 20 Jan 2023 11:26:33 -0500 Pass the vma iterator through to __vma_adjust() so the state can be updated.
