This is late in the -rc2 window because I got confused about whether I or akpm was taking this patch. I noticed it still wasn't in -mm, so here it is. It's a small Kconfig change that fixes a bunch of build warnings under KASAN and the gcc-plugin-based stack auto-initialization features (which are arguably redundant, so better to let KASAN control this). Thanks! -Kees The following changes since commit cd6c84d8f0cdc911df435bb075ba22ce3c605b07: Linux 5.2-rc2 (2019-05-26 16:49:19 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/meminit-v5.3-rc2 for you to fetch changes up to 173e6ee21e2b3f477f07548a79c43b8d9cfbb37d: structleak: disable STRUCTLEAK_BYREF in combination with KASAN_STACK (2019-07-25 16:16:12 -0700) ---------------------------------------------------------------- meminit fix - Disable gcc-based stack variable auto-init under KASAN (Arnd Bergmann) ---------------------------------------------------------------- Arnd Bergmann (1): structleak: disable STRUCTLEAK_BYREF in combination with KASAN_STACK security/Kconfig.hardening | 7 +++++++ 1 file changed, 7 insertions(+) -- Kees Cook
