When a process uses sysfs and tries to mmap more space than is available in a PCI BAR, we emit a warning and a backtrace. The mmap fails anyway, so the backtrace is mainly for debugging. But in general we don't emit kernel messages when syscalls return failure. The similar procfs mmap path simply fails the mmap with no warning. Remove the sysfs warning.

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.
