The quilt patch titled Subject: selftests/mm: fix -Wmaybe-uninitialized warnings has been removed from the -mm tree. Its filename was selftests-mm-fix-wmaybe-uninitialized-warnings.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Kevin Brodsky <kevin.brodsky@xxxxxxx> Subject: selftests/mm: fix -Wmaybe-uninitialized warnings Date: Mon, 9 Dec 2024 09:50:07 +0000 A few -Wmaybe-uninitialized warnings show up when building the mm tests with -O2. None of them looks worrying; silence them by initialising the problematic variables.
