commit620d8745b3("Introduce cifs_copy_file_range()") changes the behaviour of the cifs ioctl call CIFS_IOC_COPYCHUNK_FILE. In case of successful writes, it now returns the number of bytes written. This return value is treated as an error by the xfstest cifs/001. Depending on the errno set at that time, this may or may not result in the test failing. The patch fixes this by setting the return value to 0 in case of successful writes.

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.
