[merged mm-stable] mm-damon-tests-core-kunit-handle-alloc-failres-in-damon_test_new_filter.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/damon/tests/core-kunit: handle alloc failres in damon_test_new_filter() has been removed from the -mm tree. Its filename was mm-damon-tests-core-kunit-handle-alloc-failres-in-damon_test_new_filter.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: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/tests/core-kunit: handle alloc failres in damon_test_new_filter() Date: Sat, 1 Nov 2025 11:20:07 -0700 damon_test_new_filter() is assuming all dynamic memory allocation in it will succeed. Those are indeed likely in the real use cases since those allocations are too small to fail, but theoretically those could fail. In the case, inappropriate memory access can happen.

[merged mm-stable] mm-damon-tests-core-kunit-handle-alloc-failures-on-dasmon_test_merge_regions_of.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/damon/tests/core-kunit: handle alloc failures on dasmon_test_merge_regions_of() has been removed from the -mm tree. Its filename was mm-damon-tests-core-kunit-handle-alloc-failures-on-dasmon_test_merge_regions_of.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: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/tests/core-kunit: handle alloc failures on dasmon_test_merge_regions_of() Date: Sat, 1 Nov 2025 11:20:01 -0700 damon_test_merge_regions_of() is assuming all dynamic memory allocation in it will succeed. Those are indeed likely in the real use cases since those allocations are too small to fail, but theoretically those could fail. In the case, inappropriate memory access can happen. Fix it by appropriately cleanup pre-allocated memory and skip the execution of the remaining tests in the failure cases.
