Linux kernel source tree

For these places are protected by rcu_read_lock, we change from rcu_dereference_rtnl to rcu_dereference, as there is no need to check if rtnl lock is held. For these places are protected by rtnl_lock, we change from rcu_dereference_rtnl to rtnl_dereference/rcu_dereference_protected, as no extra memory barriers are needed under rtnl_lock() which also protects tn->bearer_list[] and dev->tipc_ptr/b->media_ptr updating. rcu_dereference_rtnl will be only used in the places where it could be under rcu_read_lock or rtnl_lock.

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.
