Module kcore::dev

Device driver.

The design should be applicable for such use cases:

• Env server
• Tempdir and tempfile: env,
• Two-way pipe: stdin/stdout, network
• Event listener on file: Epoll
• how to retrieve directory that posesses this file and then call its wstat.
• Donot support atomic renaming due to portable reason, use special ctrl file instead.
• Donot support link/unlink, use bind and mount instead. Since they provide more abstraction and behave more generally and more user-friendly.
• Donot deal with access control, just r/w permission information.

Permission in file system?

Use namespace instead?
