Linus Torvalds c574fb2ed7 A set of updates for futexes and related selftests:
- Plug the ptrace_may_access() race against a concurrent exec() which
     allows to pass the check before the target's process transition in
     exec() by taking a read lock on signal->ext_update_lock.
 
   - A large set of cleanups and enhancement to the futex selftests. The
     bulk of changes is the conversion to the kselftest harness.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

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.
