A pseudofs-based fs defines the following: - a bunch of structs listing the name, type etc. of every node in the file system (directories, files, links and device nodes) - handler functions that generate the content of the files and links, using the sbuf API - (not yet) handler functions that implement security policies (determining if the requesting process is allowed to perform the requested operation) - (not yet) handler functions that generate process-dependent nodes on demand The pseudofs code does all the rest. The ultimate goal is to reduce to a minimum the amount of code duplicated between various existing incarnations of procfs, and make it much simpler to write new ones. I hope it will also reduce the footprint of such filesystems.
