Its filename was mm-collapse-drop-the-collapse_possible-wrapper.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: "Kiryl Shutsemau (Meta)" Subject: mm/collapse: drop the collapse_possible() wrapper Date: Wed, 16 Sep 2026 10:31:33 +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.
