From 08c1d2db5fb89c66908aa8f25dade3896f1627f7 Mon Sep 17 00:00:00 2001 From: Donet Tom Date: Sat, 16 Aug 2025 09:31:07 +0530 Subject: [PATCH] mm/selftests: fix incorrect pointer being passed to mark_range() Patch series "selftests/mm: Fix false positives and skip unsupported tests", v4. This patch series addresses false positives in the generic mm selftests and skips tests that cannot run correctly due to missing features or system limitations. This patch (of 7): In main(), the high address is stored in hptr, but for mark_range(), the address passed is ptr, not hptr. Fixed this by changing ptr[i] to hptr[i] in mark_range() function call.
