From f80ddc148ca6505060fbef6f8365ca151103e16f Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Wed, 5 Feb 2025 17:27:15 +0800 Subject: [PATCH] mm/swapfile.c: update the code comment above swap_count_continued() Now, swap_count_continued() has two callers, __swap_duplicate() and __swap_entry_free_locked(), the relevant code comment is stale. Update it to reflect the current situation.
