Removing ReiserFS from the Linux kernel: A significant turning point for the operating system

In the vast ecosystem of Linux operating system, each modification of the kernel is subject to particular attention. Recently, Linux kernel 6.13 decided to remove the ReiserFS file system, a change that marks an important step in the evolution of data management on Linux. This article explores the implications of this decision for developers and users.

A look back at the history of ReiserFS

THE ReiserFS file system was first integrated into Linux over 20 years ago. Originally designed by Hans Reiser To provide optimized performance in file management, ReiserFS evolved over time but gradually lost popularity. Several reasons explain this decline:

  • Official deprecation : ReiserFS has been marked as deprecated in the kernel as of 2022.
  • Lack of updates : General interest in ReiserFS has declined, making its adoption less attractive.
  • Modern alternatives : Other file systems such as Ext4 And Btrfs have been able to capture the attention of users thanks to their advanced features.

Removing ReiserFS represents a significant lightweighting of the kernel, with approximately 32.8k lines of code removed. This code reduction has several advantages:

  • Performance Optimization : Less code means a lighter and potentially more responsive core.
  • Simplification of maintenance : Developers will be able to focus their efforts on more commonly used file systems.

Impact on users and businesses

Although the removal of ReiserFS does not appear to have an immediate impact, it raises several questions for business users, including:

⚙️ Consequences for users Options to Consider
👥 Users using ReiserFS Ability to downgrade to an earlier kernel version to maintain access to ReiserFS formatted disks.
📦 Businesses Reassessment of data storage strategy and migration to more current alternatives.

Future without ReiserFS

With ReiserFS now removed from the core, the future of storage in Linux seems more oriented towards other file systems, reinforcing the importance of Btrfs And Ext4**. This event could indicate a refocusing on evolving technologies better adapted to contemporary needs.

Users and developers will therefore have to remain vigilant and adapt their practices according to developments in the kernel. What will be the next steps in the development of Linux file systems? What alternatives do your companies choose? Share your thoughts in the comments!
