From f04cc63dc7d0b7b5ce71477584377c99ba2ba4bf Mon Sep 17 00:00:00 2001 From: Ye Liu Date: Mon, 21 Apr 2025 16:57:28 +0800 Subject: [PATCH] mm/rmap: rename page__anon_vma to anon_vma for consistency Patch series "mm: minor cleanups in rmap", v3. Minor cleanups in mm/rmap.c: - Rename a local variable for consistency - Fix a typo in a comment No functional changes. This patch (of 2): Rename local variable page__anon_vma in page_address_in_vma() to anon_vma. The previous naming convention of using double underscores (__) is unnecessary and inconsistent with typical kernel style, which uses single underscores to denote local variables. Also updated comments to reflect the new variable name. Functionality unchanged.
