I do have patches for ext4, ocfs2 and xfs to use this, but they're too
late now for v3.4.  However, it would be helpful if this function could
go ahead into v3.4, so filesystems can convert to it at leisure afterwards.

I just sent out the little ext4 and xfs patches, but decided not
to bother you with the ocfs2 one.  ocfs2 is already doing it right with
unmap_mapping_range; and since file.c is using unmap_mapping_range with
truncate_inode_pages in other places, it seemed wrong to force a different
convention upon you in this one place (perhaps they can all be converted
to truncate_pagecache_range, but if it ain't broke...)

Works for me.  Thanks.
