Subject: [Proposed Fix v1] t5318: replace dd if=/dev/zero with truncate
Date: Fri, 8 Feb 2019 14:28:18 -0500 [thread overview]
Message-ID: <20190208192818.21488-1-randall.s.becker@rogers.com> (raw)
From: "Randall S. Becker" <rsbecker@nexbridge.com>
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.
