[PATCH v2 0/3] Actually fix freelist pointer vs redzoning

[Kees Cook]

v2:
- add additional clean-up patches
- add Tested-by
v1: https://lore.kernel.org/lkml/20201008233443.3335464-1-keescook@xxxxxxxxxxxx

This fixes redzoning vs the freelist pointer (both for middle-position
and very small caches). Both are "theoretical" fixes, in that I see no
evidence of such small-sized caches actually be used in the kernel, but
that's no reason to let the bugs continue to exist. :)

Thanks!
