The rcu_data_p pointer references the default set of per-CPU rcu_data structures, that is, those that call_rcu() uses, as opposed to call_rcu_bh() and sometimes call_rcu_sched(). But there is now only one set of per-CPU rcu_data structures, so that one set is by definition the default, which means that the rcu_data_p pointer no longer serves any useful purpose. This commit therefore removes it. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
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.
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.
