From 81dd246d953585c08984aa4b059d8c1ee1c8e715 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Tue, 23 Jan 2018 17:22:30 +0100 Subject: [PATCH] btrfs-progs: tests: truncate test image to 0 first We use the prepare_test_dev helper to make sure the image has at least this size. The "at least" part is not desired by some tests as the device might be larger than the test expects.
