From f83bd24e3d22838de63e856f4e52234a1ed518d4 Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Wed, 5 Feb 2025 17:27:20 +0800 Subject: [PATCH] mm/swapfile.c: remove the incorrect code comment Since commit eb085574a752 ("mm, swap: fix race between swapoff and some swap operations"), the non_swap_entry() checking has been taken off from function __swap_duplicate(). Hence, in the kernel-doc comment, the line 'swp_entry is migration entry -> EINVAL' is obsolete. Remove that line to avoid misleading people.
