From 54d6adf7c98500a177f0507c5905ed6dfb2fa888 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 29 Jul 2013 14:55:56 -0400 Subject: [PATCH] xfstests: generic/315: allow a little tolerance for our used check So df in btrfs is tricky at best, and relying on it for accurate information is not great, but it's the best way to verify this test. To get around btrfs being inconsistent sometimes just use _within_tolerance to check our new df value to make sure that our truncate did something. With this patch I no longer see transient failures of this test.
