From 67d782514941a68ea47934379e2d96050c9b2001 Mon Sep 17 00:00:00 2001 From: "Igor Mikhailov (imichail)" Date: Mon, 5 Feb 2018 12:09:36 -0800 Subject: 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.
