memfs

Documentation

Overview

Package memfs provides a filesystem implementation that behaves like tmpfs: the Dentry tree is the sole source of truth for the state of the filesystem.

memfs is intended primarily to demonstrate filesystem implementation patterns. Real uses cases for an in-memory filesystem should use tmpfs instead.

Lock order:

filesystem.mu

regularFileFD.offMu
  regularFile.mu
