Subject: [PATCH 2/5] btrfs: correct a message on setting nodatacow
Date: Thu, 18 Sep 2014 17:28:13 +0900	[thread overview]
Message-ID: <541A979D.8060409@jp.fujitsu.com> (raw)
In-Reply-To: <541A9717.5000003@jp.fujitsu.com>

From: Naohiro Aota <naota@elisp.net>

If we set nodatacow mount option after compress-force option,
we don't get compression disabling message.

===
$ sudo mount -o remount,compress-force,nodatacow /; dmesg|tail -n 3
[ 3845.719047] BTRFS info (device vda2): force zlib compression
[ 3845.719052] BTRFS info (device vda2): setting nodatacow
[ 3845.719055] BTRFS info (device vda2): disk space caching is enabled
