Subject: [PATCH 2/2] mm/swapfile: use plist_for_each_entry in __folio_throttle_swaprate
Date: Wed, 26 Nov 2025 01:30:27 +0900 [thread overview]
Message-ID: <20251125163027.4165450-3-youngjun.park@lge.com> (raw)
In-Reply-To: <20251125163027.4165450-1-youngjun.park@lge.com>
The loop breaks immediately after finding the first swap device and
never modifies the list. Replace plist_for_each_entry_safe() with
plist_for_each_entry() and remove the unused next variable.
