Pull tracing fixes from Steven Rostedt: - Bring back context level recursive protection in ring buffer. The simpler counter protection failed, due to a path when tracing with trace_clock_global() as it could not be reentrant and depended on the ring buffer recursive protection to keep that from happening. - Prevent branch profiling when FORTIFY_SOURCE is enabled. It causes 50 - 60 MB in warning messages. Branch profiling should never be run on production systems, so there's no reason that it needs to be enabled with FORTIFY_SOURCE. * tag 'trace-v4.15-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Prevent PROFILE_ALL_BRANCHES when FORTIFY_SOURCE=y ring-buffer: Bring back context level recursive checks
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.
