vmtruncate is a deprecated function so it'd be better to remove it.
The truncate sequence is changed for several reasons. The
documentation is clear: "This function is deprecated and
truncate_setsize or truncate_pagecache should be used instead,
together with filesystem specific block truncation." In addition, we
can remove the truncate callback from the inode struct saving 4/8
bytes.
