From 0a1e082b64ccce165e7307a7b49d22b2504f9d1f Mon Sep 17 00:00:00 2001 From: Liu Ye Date: Wed, 19 Mar 2025 17:17:26 +0800 Subject: [PATCH] mm/page_alloc: remove unnecessary __maybe_unused in order_to_pindex() The `movable` variable is always used when `CONFIG_TRANSPARENT_HUGEPAGE` is enabled, so the `__maybe_unused` attribute is not necessary. This patch removes it and keeps the variable declaration within the `#ifdef` block for better clarity.
