Merge tag 'array-bounds-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull array-bounds updates from Kees Cook:
"This enables -Warray-bounds and -Wzero-length-bounds, now that the
many bug fixes have landed all over the place in the kernel, and in
GCC itself[1].
A couple fixes[2] for known corner-case issues currently live in my
"pending-fixes" tree which I'm expecting to send next week if other
maintainers still haven't picked them up.
I'm also expecting we can enable -Wstringop-overflow next cycle, as
there are only a few stragglers[3], but it might even be possible for
this release"
