commit a10c21ed5d5241d11cf1d5a4556730840572900b upstream. [Slightly edit xfs_dir3_data_read() to work with existing mapped_bno argument instead of flag values introduced in later kernels] Check the owner field of dir3 data block headers. If it's corrupt, release the buffer and return EFSCORRUPTED. All callers handle this properly. Signed-off-by: Darrick J.

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.
