commit 26d75a16af285a70863ba6a81f85d81e7e65da50 upstream. If a block is out of range in ext4_get_branch(), -ENOMEM will be returned to user-space. Obviously, this error code isn't really useful. This patch fixes it by making sure the right error code (-EFSCORRUPTED) is propagated to user-space. EUCLEAN is more informative than ENOMEM.

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.
