Mastering Linux Kernel Development

Filesystems in the Linux kernel

Now that we are familiar with fundamental concepts related to filesystem implementations, we will explore filesystem services supported by Linux systems. The kernel's filesystem branch has implementations of numerous filesystem services, which support diverse file types. Based on the type of files they manage, the kernel's filesystems can be broadly categorized into:

1. Storage filesystems
2. Special filesystems
3. Distributed filesystems or network filesystems

We shall discuss special filesystems in a later section of this chapter.

• Storage filesystems: Kernel supports various persistent storage filesystems, which can be broadly categorized into various groups based on the type of storage device they are designed ...
