[PATCH] maple_tree: Add dead node check in mas_dup_alloc()

Just to confirm: do you want me to remove the original runtime check entirely
and replace it with a lockdep_assert(), or do you want both?
If it's only the assertion,
that would mean that production builds won't enforce the check, right?

For v2, should I add a Fixes: line and Cc: stable,
or should i leave it out?

Also, do you want me to include a Suggested-by tag
for your lockdep_assert suggestion?

Thanks,
Boudewijn
