     Subject: mm/collapse: drop the collapse_possible() wrapper

From: "Kiryl Shutsemau (Meta)" <kas@kernel.org>
Subject: mm/collapse: drop the collapse_possible() wrapper
Date: Thu, 10 Sep 2026 13:02:26 +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.
