Subject: [PATCH] fstests: btrfs/091: Disable compress to avoid output dismatch
Date: Tue, 12 Apr 2016 15:59:58 +0800	[thread overview]
Message-ID: <1460447998-6899-1-git-send-email-quwenruo@cn.fujitsu.com> (raw)

If run btrfs/091 with "-o compress=lzo" mount option, test case will
fail, as compress makes extent much smaller on disk, making output
different from golden output.

As this test case is only testing qgroup, not compression, disable
compression manually in test case.
