Hmm. I wonder if we should have made the i_size_read/write helpers be
smp_load_acquire/store_release()?

The existing smp_wmb() are almost accidental, and aren't primarily
about the inode size, but about the page/folio uptodate bit. I guess
they work, but it's all a bit messy.

Which might *also* be better off with acquire/release, but we don't
have those bitops, I guess. Oh well.
