[ Upstream commit a9201960623287927bf5776de3f70fb2fbde7e02 ]
This fixes an analogus bug that was fixed in modern filesystems:
a) xfs in commit 4b8d867ca6e2 ("xfs: don't over-report free space or
inodes in statvfs")
b) ext4 in commit f87d3af74193 ("ext4: don't over-report free space
or inodes in statvfs")
where statfs can report misleading / incorrect information where
project quota is enabled, and the free space is less than the
remaining quota.
This commit will resolve a test failure in generic/762 which tests
for this bug.

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.
