I applied your CONFIG_KASAN_VMALLOC on top of 5.5-rc6 and applied your VMAP_STACK series afterwards. # grep -i kasan .config CONFIG_HAVE_ARCH_KASAN=3Dy CONFIG_HAVE_ARCH_KASAN_VMALLOC=3Dy CONFIG_CC_HAS_KASAN_GENERIC=3Dy CONFIG_KASAN=3Dy CONFIG_KASAN_GENERIC=3Dy # CONFIG_KASAN_OUTLINE is not set CONFIG_KASAN_INLINE=3Dy CONFIG_KASAN_STACK=3D1 CONFIG_KASAN_VMALLOC=3Dy # CONFIG_TEST_KASAN is not set CONFIG_KASAN_SHADOW_OFFSET=3D0xe0000000 # grep -i vmap .config CONFIG_HAVE_ARCH_VMAP_STACK=3Dy CONFIG_VMAP_STACK=3Dy --=20 You are receiving this mail because: You are watching the assignee of the bug.=
