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.

Pull two more ftrace fixes from Steven Rostedt: "While continuing my development, I uncovered two more small bugs. One is a race condition when enabling the snapshot function probe trigger. It enables the probe before allocating the snapshot, and if the probe triggers first, it stops tracing with a warning that the snapshot buffer was not allocated. The seconds is that the snapshot file should show how to use it when it is empty. But a bug fix from long ago broke the "is empty" test and the snapshot file no longer displays the help message" * tag 'trace-v4.11-rc5-5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ring-buffer: Have ring_buffer_iter_empty() return true when empty tracing: Allocate the snapshot buffer before enabling probe
