In the past it was usually enough to just align it to alignof(unsigned
long), not actually make it long. struct page went through this
a long time ago.

This could cause r-m-w races with the next field in theory, but assuming
it's reasonably read-only (ie only set up at inode creation time)
that should be fine.
