This commit adds support for smp_mb__after_srcu_read_unlock(), which, when combined with a prior srcu_read_unlock(), implies a full memory barrier. No ordering is guaranteed to accesses between the two, and placing accesses between is bad practice in any case. Tests may be found at https://github.com/paulmckrcu/litmus in files matching manual/kernel/C-srcu-mb-*.litmus. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
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 Restructured Text 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.
