Description of the problem

  • statfs.bsize fails to mention if the size is reported in bits or bytes
  • While statfs.bavail and statfs.bfree can be used to calculate available and free space, it would be appropriate to put an example on how to use them Example: 
    import { statfs } from "fs/promises"
const statsfs = await statfs("/tmp")
const available_bits_or_bytes_not_documented = statsfs.bsize * statsfs.bavail
  • Similarly, statfs.blocks and statfs.files would strongly benefit from an example
  • What's statfs.type and why is it a number?

研究方向
The issue requests clarifications and examples for properties of the `StatFs` class in the Node.js `fs` documentation, specifically `bsize`, `bavail`, `bfree`, `blocks`, `files`, and `type`. The relevant file is likely `doc/api/fs.md` in the Node.js repository. The maintainer may have already commented on the correct units and usage. To address this, review the existing documentation and any linked references (e.g., POSIX `statvfs`). Then update the description to specify that `bsize` is in bytes, provide a code example showing how to calculate available space, and explain that `type` refers to the filesystem type identifier (e.g., from Linux's `f type` header).
