disk_usage(path) confusion

[MrBillium]

It appears that disk_usage (path) does not report the size of the directory tree in the specified path but instead reports the size of the partition | mountpoint that contains the path.

This is not what I expected and the current documentation does not describe this behavior:

psutil.disk_usage(path)[source]
Return disk usage statistics about the given path as a named tuple including total, used and free space expressed in bytes, plus the percentage usage. OSError is raised if path does not exist.

I suggest updating the documentation to make it clear that you do not get the disk used by the 'path'.
Better still, modify code to actually report the disk used by the path - like du command

OK, changed to:

Return disk usage statistics about the partition which contains the given
path as a named tuple including total, used and free space
expressed in bytes, plus the percentage usage.
