The fallback implementation for the get_name export operation uses readdir() to try to match the inode number to a filename. That filename is then used together with lookup_one() to produce a dentry. A problem arises when we match the '.' or '..' entries, since that causes lookup_one() to fail. This has sometimes been seen to occur for filesystems that violate POSIX requirements around uniqueness of inode numbers, something that is common for snapshot directories. This patch just ensures that we skip '.' and '..' rather than allowing a match.

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.
