grumble, mutter. It's certainly simple enough.
+ mapping = vma->vm_file->f_dentry->d_inode->i_mapping;
I'm not so sure about this one now. write() alters dentry->d_inode but truncate alters dentry->d_inode->i_mapping->host. Unless truncate is changed we have the wrong mapping here.
I'll put it back to the original while I try to work out why truncate isn't wrong...
