Hmm. I wonder what makes it valid to have concurrent updates to
i_size? Yes, yes, you added that spinlock to make the update itself
atomic on 32-bit, but it sounds a bit odd in the first place to have
two things possibly changing the size of a file at the same time...

Anyway, pulled, but just surprised...
