commit 4268496e48dc681cfa53b92357314b5d7221e625 upstream. Like ext4_ext_rm_leaf, we can ensure that there are enough credits before every call that will consume credits. As part of this fix we fold the functionality of ext4_access_path() into ext4_ext_shift_path_extents(). This change is needed as a preparation for the next bugfix patch.

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.
