\opening{Dear Mr. Reiser,}

I am writing to you regarding the current state of filesystem development in the Linux kernel. As you are no doubt aware, ReiserFS is scheduled to be removed from the kernel—

\begin{verbatim}
From eb103a51640ee32ab01c51e13bf8fca211f25f61 Mon Sep 17 00:00:00 2001
From: Jan Kara <jack@suse.cz>
Date: Fri, 25 Feb 2022 13:54:45 +0100
Subject: reiserfs: Deprecate reiserfs

Reiserfs is relatively old filesystem and its development has ceased
quite some years ago. Linux distributions moved away from it towards
other filesystems such as btrfs, xfs, or ext4. To reduce maintenance
burden on cross filesystem changes (such as new mount API, iomap, folios
...) let's add a deprecation notice when the filesystem is mounted and
schedule its removal to 2025.
