commit bb3d48dcf86a97dc25fe9fc2c11938e19cb4399a upstream. xfs_attr3_leaf_create may have errored out before instantiating a buffer, for example if the blkno is out of range. In that case there is no work to do to remove it, and in fact xfs_da_shrink_inode will lead to an oops if we try. This also seems to fix a flaw where the original error from xfs_attr3_leaf_create gets overwritten in the cleanup case, and it removes a pointless assignment to bp which isn't used after this.

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.
