Its filename was mm-collapse-drop-the-collapse_possible-wrapper.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: "Kiryl Shutsemau (Meta)" Subject: mm/collapse: drop the collapse_possible() wrapper Date: Wed, 14 Oct 2026 18:11:39 +0100 collapse_possible() only forwards to collapse_possible_orders() and turns its mask into a bool. Its three callers can test the mask themselves. No functional change.
