[PATCH] D119816: Fix not working attribute no_sanitize bounds that affects linux kernel

[Nuno Lopes via Phabricator via llvm-commits]

Well, this patch is just a band-aid and a disaster waiting to happen.
If kmalloc is tagged with an __attribute__ stating the allocation size, then you can't dereference beyond that limit or risk the alias analysis do something you don't want. You are triggering UB like that.
Can't you just remove the __attribute__ from kmalloc instead to avoid triggering UB?
