Subject[PATCH v4 0/3] Actually fix freelist pointer vs redzoning
Date
v4:
- remove redundant size check
v3: https://lore.kernel.org/lkml/20201015033712.1491731-1-keescook@chromium.org
v2: https://lore.kernel.org/lkml/20201009195411.4018141-1-keescook@chromium.org

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, especially since
people doing local development keep tripping over it. :)

Thanks!
