Commit4f016420d3("Staging: lustre: obdclass: Use kasprintf") moved some sprintf() calls earlier in the code to combine them with memory allocation and create kasprintf() calls. In one case, this code movement moved the sprintf to a location where the values being formatter were different. In particular sprintf(niduuid, "%s_%x", mgcname, i); was move from *after* the line i = 0; to a location where the value of 'i' was at least 1. This cause the wrong name to be formatted, and triggers CERROR("del MDC UUID %s failed: rc = %d\n", niduuid, rc); at unmount time. So use '0' instead of 'i'.

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.
