Subject: [PATCH] btrfs-progs: add the error message when open fails
Date: Thu, 09 Jun 2016 10:23:15 +0900 [thread overview]
Message-ID: <201606090123.AA00000@WIN-5MHF4RKU941.jp.fujitsu.com> (raw)
When open in btrfs_open_devices failed, only the following message is
displayed. Therefore the user doesn't understand the reason why open
failed.
# btrfs check /dev/sdb8
Couldn't open file system
This patch adds the error message when open fails.
