Its filename was fb_defio-do-not-use-deprecated-page-mapping-index-fields-fix.patch This patch was dropped because it was folded into fb_defio-do-not-use-deprecated-page-mapping-index-fields.patch ------------------------------------------------------ From: Lorenzo Stoakes Subject: mm: fixup unused variable warnings Date: Sun, 9 Feb 2025 06:29:25 +0000 Unfortunately fb_defio being enabled by nommu devices seems enormously ingrained in the kernel to the point that it's not feasible to address that in this series, so we use an ifdef to workaround. However this workaround unfortunately missed some unused variables - correct this. This has been tested locally with W=1 and confirmed to resolve the issue.
