Provide page-aligned length to ftruncate.
For some files such as hugepages files, ftruncate() fails with the error "Invalid argument" if the 'length' parameter is not on a page boundary. Change-Id: I42a9cde98707da15e3c5d1653046e2277fc7a424 Signed-off-by: Igor Mikhailov (imichail) <imichail@cisco.com>
