ext4: truncate_inode_pages() in orphan cleanup path
Currently we do not tell mm to zero out tail of the page before truncate
in orphan_cleanup(). This is ok, because the page should not be
uptodate, however this may eventually change and I might cause problems.
Call truncate_inode_pages() as precautionary measure. Thanks Jan Kara
for pointing this out.
