From 826550dcd46d42c0aa667e69cdcb71a485b19a5c Mon Sep 17 00:00:00 2001 From: Guanjun Date: Thu, 13 Feb 2025 13:56:12 +0800 Subject: [PATCH] filemap: remove redundant folio_test_large check in filemap_free_folio The folio_test_large() check in filemap_free_folio() is unnecessary because folio_nr_pages(), which is called internally already performs this check. Removing the redundant condition simplifies the code and avoids double validation. This change improves code readability and reduces unnecessary operations in the folio freeing path.
