commit 996fc4477a0ea28226b30d175f053fb6f9a4fa36 upstream. It's possible for ext4_get_acl() to return an ERR_PTR. So we need to add a check for this case in __ext4_new_inode(). Otherwise on an error we can end up oops the kernel. This was getting triggered by xfstests generic/388, which is a test which exercises the shutdown code path.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
