Kernels built with the CONFIG_TREE_SRCU Kconfig option set and then booted with rcupdate.rcu_self_test=1 and srcutree.convert_to_big=1 will test Tree SRCU during early boot. The early_srcu structure's srcu_node array will be allocated when init_srcu_struct_fields() is invoked, but after the test completes this early_srcu structure will not be used. This commit therefore invokes cleanup_srcu_struct() to free that srcu_node structure. Signed-off-by: Zqiang <qiang1.zhang@intel.com> 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.
