It may be - I just did what Al told me without really understanding it ;-)

The test I did initially was the following:

if(!atomic_read(&bh->b_count) &&
        (destroy_dirty_buffers || !buffer_dirty(bh))
        && ! (bh->b_page && bh->b_page->mapping)
        )

That is, I was explicitely checking for a mapped page. It worked well, too.
Is this more reasonable?
