If a process dumps core while it has SPU contexts active then we have code to also dump information about the SPU contexts. Unfortunately it's been broken for 3 1/2 years, and we didn't notice. In commit7b1f4020d0("spufs: get rid of dump_emit() wrappers") the nread variable was removed and rc used instead. That means when the loop exits successfully, rc has the number of bytes read, but it's then used as the return value for the function, which should return 0 on success. So fix it by setting rc = 0 before returning in the success case.

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.
