Subject: [PATCH V7 09/19] famfs_fuse: magic.h: Add famfs magic numbers
Date: Sun, 18 Jan 2026 22:32:32 +0000 [thread overview]
Message-ID: <0100019bd33d0dd3-81bc3562-6f64-4689-9312-6b6cec095540-000000@email.amazonses.com> (raw)
In-Reply-To: <0100019bd33b1f66-b835e86a-e8ae-443f-a474-02db88f7e6db-000000@email.amazonses.com>
From: John Groves <john@groves.net>
Famfs distinguishes between its on-media and in-memory superblocks. This
reserves the numbers, but they are only used by the user space
components of famfs.
