[PATCH 00/22] mm/damon/tests: fix memory bugs in kunit tests

by SeongJae Park

DAMON kunit tests were initially written assuming those will be run on environments that are well controlled and therefore tolerant to transient test failures and bugs in the test code itself. The user-mode linux based manual run of the tests is one example of such an environment. And the test code was written for adding more test coverage as fast as possible, over making those safe and reliable. As a result, the tests resulted in having a number of bugs including real memory leaks, theoretical unhandled memory allocation failures, and unused memory allocations. The allocation failures that are not handled well are unlikely in the real world, since those allocations are too small to fail. But in theory, it can happen and cause inappropriate memory access. It is arguable if bugs in test code can really harm users. But, anyway bugs are bugs that need to be fixed. Fix the bugs one by one. Also Cc stable@ for the fixes of memory leak and unhandled memory allocation failures. The unused memory allocations are only a matter of memory efficiency, so not Cc-ing stable@. The first patch fixes memory leaks in the test code for the DAMON core layer. Following fifteen, three, and one patches respectively fix unhandled memory allocation failures in the test code for DAMON core layer, virtual address space DAMON operation set, and DAMON sysfs interface, one by one per test function. Final two patches remove memory allocations that are correctly deallocated at the end, but not really being used by any code.
