Zijun Hu 84ead78a3c fs/filesystems: Fix potential unsigned integer underflow in fs_name()
[ Upstream commit 1363c134ade81e425873b410566e957fecebb261 ]

fs_name() has @index as unsigned int, so there is underflow risk for
operation '@index--'.

Fix by breaking the for loop when '@index == 0' which is also more proper
than '@index <= 0' for unsigned integer comparison.

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.
