Chengguang Xu c26b97c9c9 f2fs: fix miscounted block limit in f2fs_statfs_project()
statfs calculates Total/Used/Avail disk space in block unit,
so we should translate soft/hard prjquota limit to block unit
as well.

Below testing result shows the block/inode numbers of
Total/Used/Avail from df command are all correct afer
applying this patch.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
