Having two fields for the same purpose with subtle differences on different RCU flavours is confusing, especially when both fields always exist on both RCU flavours. Fortunately, it is now safe for preemptible RCU to rely on the rcu_data structure's ->cpu_no_qs.b.exp field, just like non-preemptible RCU. This commit therefore removes the ad-hoc ->exp_deferred_qs field. Signed-off-by: Frederic Weisbecker <frederic@kernel.org> 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.
