===============================
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.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
