commit 4559b0a71749c442d34f7cfb9e72c9e58db83948 upstream. If we're trying to make a data reservation and we have to allocate a data chunk we could leak ret == 1, as do_chunk_alloc() will return 1 if it allocated a chunk. Since the end of the function is the success path just return 0.

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.
