Its filename was mm-constify-assert-test-functions-in-mmh.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: Max Kellermann Subject: mm: constify assert/test functions in mm.h Date: Mon, 1 Sep 2025 22:50:20 +0200 For improved const-correctness. We select certain assert and test functions which either invoke each other, functions that are already const-ified, or no further functions. It is therefore relatively trivial to const-ify them, which provides a basis for further const-ification further up the call stack.
