Subject: [PATCH v2] fstests: btrfs: check conversion of zoned fileystems
Date: Tue, 13 Feb 2024 00:20:31 -0800 [thread overview]
Message-ID: <20240213082031.1943895-1-johannes.thumshirn@wdc.com> (raw)
Recently we had a bug where a zoned filesystem could be converted to a
higher data redundancy profile than supported.
Add a test-case to check the conversion on zoned filesystems.
