From: randall.s.becker@rogers.com Date: Fri, 08 Feb 2019 19:28:18 GMT Subject: [Proposed Fix v1] t5318: replace dd if=/dev/zero with truncate Message-ID: <20190208192818.21488-1-randall.s.becker@rogers.com> From: "Randall S. Becker" The corrupt_graph_and_verify method has been modified to use truncate instead of the /dev/zero pseudo-device, which breaks on platforms where the pseudo-device does not exist. truncate extends files to a specified length filling with nulls, providing a similar function to the use of dd in this case.
