Problem: The statfs reports incorrect free/available space for quota less then CEPH_BLOCK size (4M). Solution: For quota less than CEPH_BLOCK size, smaller block size of 4K is used. But if quota is less than 4K, it is decided to go with binary use/free of 4K block. For quota size less than 4K size, report the total=used=4K,free=0 when quota is full and total=free=4K,used=0 otherwise.

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.
