Unfortunately the bpf tree has been making changes in the same area of
memcontrol.c.  01d37228d331 ("memcg: Use trylock to access memcg
stock_lock.")

Sigh.  We're at -rc7 and I don't think it's worth working around that
for a cleanup series.  So I'm inclined to just defer this series until
the next -rc cycle.

If BPF merges reasonably early in the next merge window then please
promptly send this along and I should be able to squeak it into
6.15-rc1.
