reiserfs: Deprecate reiserfs

Browse Source 
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.

Stores not just filenames but the files themselves in a balanced
tree. Uses journalling.
Reiserfs is deprecated and scheduled to be removed from the kernel
in 2025. If you are still using it, please migrate to another
filesystem or tell us your usecase for reiserfs.
Reiserfs stores not just filenames but the files themselves in a
balanced tree. Uses journalling.
Balanced trees are more efficient than traditional file system
architectural foundations.
