[ Upstream commit 26b66d1d366a375745755ca7365f67110bbf6bd5 ] The get_parent handler looks up a parent of a given dentry, this can be either a subvolume or a directory. The search is set up with offset -1 but it's never expected to find such item, as it would break allowed range of inode number or a root id. This means it's a corruption (ext4 also returns this error code).

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.
