Subject: [RFC PATCH v3 9/9] btrfs: test snapshotting encrypted subvol
Date: Tue, 8 Aug 2023 13:21:28 -0400 [thread overview]
Message-ID: <400435f749f54e07a23e8e3c67bb717646747cc4.1691530000.git.sweettea-kernel@dorminy.me> (raw)
In-Reply-To: <cover.1691530000.git.sweettea-kernel@dorminy.me>
Make sure that snapshots of encrypted data are readable and writeable.
Test deliberately high-numbered to not conflict.
