https://nodejs.org/api/fs.html#class-fsstatfs
statfs.bsize fails to mention if the size is reported in bits or bytesstatfs.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
statfs.blocks and statfs.files would strongly benefit from an examplestatfs.type and why is it a number?
