B & C variants show this message and A does not, which is what I would expect to happen. Tested variants: A. "page_poison=1 init_on_free=0 init_on_alloc=0 slub_debug=P" B. "page_poison=1 init_on_free=0 init_on_alloc=0 slub_debug=P init_on_free=1" C. "page_poison=1 slub_debug=P" in common: CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y CONFIG_INIT_ON_FREE_DEFAULT_ON=y CONFIG_PAGE_POISONING=y CONFIG_SLUB_DEBUG=y CONFIG_SLUB=y (the slub parts don't matter, ignore them) [...] While both patches(Sergei's, and yours) work for me, I'll be using this one for now. Thank you for your work! Cheers!
Awesome; thanks for testing it! -Kees -- Kees Cook
