Subject: mm/swap_state.c: fix the obsolete code comment
Date: Wed, 5 Feb 2025 17:27:10 +0800

Patch series "Tiny cleanup and improvements about SWAP code".

These are all made during review and from reading the patchset "[PATCH v3
00/13] mm, swap: rework of swap allocator locks" from Kairui.


This patch (of 12):

Since commit 85a1333417a7 ("mm/swap: use dedicated entry for swap in
folio"), there's a dedicated field in folio for swap entry.  Let's update
the code comment above add_to_swap_cache() accordingly.
