Linux 7.3 Expected To Upstream FailFS
Linux 7.3 is expected to upstream FailFS, a new filesystem that returns EOPNOTSUPP for every operation. FailFS is a sibling of NULLFS, which provides a permanently empty and immutable directory.

Linux 7.3 is expected to upstream FailFS, a new filesystem that returns EOPNOTSUPP for every operation. FailFS is a sibling of NULLFS, which provides a permanently empty and immutable directory. This new filesystem is designed to be used during early boot and is not visible in /proc/filesystems.
Imagine you have a big box of toys, but the box is empty and you can't play with any of the toys. That's kind of like what FailFS is - a special kind of box that is empty and can't be played with. It's useful for certain situations where you need to start from a clean slate.
Analysis
A New Filesystem for Early Boot
The Linux kernel has a new filesystem in the works, called FailFS. FailFS is a sibling of NULLFS, which provides a permanently empty and immutable directory. While NULLFS is useful for certain use cases, FailFS takes it a step further by returning EOPNOTSUPP for every operation. This makes it ideal for use during early boot, where a process needs to start from a clean slate.
How FailFS Works
FailFS is designed to be used during early boot, where a process needs to start from a clean slate. It is not visible in /proc/filesystems, making it difficult to mount or clone. This is by design, as FailFS is meant to be used in a specific scenario where a process needs to shed its filesystem state completely.
The Benefits of FailFS
The benefits of FailFS are numerous. For one, it provides a new way for processes to start from a clean slate. This can be useful in certain scenarios where a process needs to start from a known state. Additionally, FailFS is designed to be used during early boot, making it ideal for use in embedded systems or other devices where a process needs to start from a clean slate.
The Road Ahead
The upstreaming of FailFS in Linux 7.3 is a significant development. It provides a new way for processes to start from a clean slate, and is designed to be used during early boot. As the Linux kernel continues to evolve, it will be interesting to see how FailFS is used in the future.
Key points
- Linux 7.3 is expected to upstream FailFS, a new filesystem that returns EOPNOTSUPP for every operation.
- FailFS is a sibling of NULLFS, which provides a permanently empty and immutable directory.
- FailFS is designed to be used during early boot and is not visible in /proc/filesystems.
The upstreaming of FailFS in Linux 7.3 could lead to new and innovative use cases for the Linux kernel. It provides a new way for processes to start from a clean slate, which could be useful in a variety of scenarios.
The upstreaming of FailFS in Linux 7.3 could also lead to new security risks. If FailFS is not properly implemented, it could potentially be used to create a backdoor or other security vulnerability.
