Filesystems in the Linux kernel¶
This under-development manual will, some glorious day, provide comprehensive information on how the Linux virtual filesystem (VFS) layer works, along with the filesystems that sit below it. For now, what we have can be found below.
Core VFS documentation¶
See these manuals for documentation about the VFS layer itself and how its algorithms work.
Filesystem support layers¶
Documentation for the support code within the filesystem layer for use in filesystem implementations.
