From f1bae15c6ad59870eca7824c66e40ee7469ee0fd Mon Sep 17 00:00:00 2001 From: Youngjun Park Date: Fri, 31 Oct 2025 15:50:09 +0900 Subject: [PATCH] mm, swap: remove redundant comment for read_swap_cache_async The function now manages get/put_swap_device() internally, making the comment explaining this behavior to callers unnecessary.
