Subject: [PATCH v4 06/10] btrfs: test case prerequisite _require_btrfs_mkfs_uuid_option
Date: Thu, 29 Feb 2024 07:19:23 +0530	[thread overview]
Message-ID: <773b7278b53dce51f6d0a797f9ffa1b3efdefe50.1709162170.git.anand.jain@oracle.com> (raw)
In-Reply-To: <cover.1709162170.git.anand.jain@oracle.com>

For easier and more effective testing of btrfs tempfsid, newer versions
of mkfs.btrfs contain options such as --device-uuid. Check if the
currently running mkfs.btrfs contains this option.
