Its filename was mm-kconfig-drop-redundant-dependency-wrappers.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: Kaitao Cheng Subject: mm/kconfig: drop redundant dependency wrappers Date: Sun, 12 Jul 2026 17:33:26 +0800 Some mm Kconfig entries repeat dependencies that are already expressed by their surrounding blocks or menus. The zsmalloc allocator options menu already depends on ZSMALLOC, so the outer if ZSMALLOC block does not add any extra constraint. MEMORY_HOTREMOVE and MHP_MEMMAP_ON_MEMORY are both inside the if MEMORY_HOTPLUG block, so their local depends on MEMORY_HOTPLUG entries are redundant. PTE_MARKER_UFFD_WP is the only entry under if USERFAULTFD. Move the USERFAULTFD dependency into the symbol itself and combine it with the architecture support dependency. This keeps the same visibility and defaults while avoiding duplicate dependency expressions.
