Introduce the rcu_replace_pointer_rtnl helper to lockdep check rtnl lock rcu replacements, alongside the already existing helpers. This is a quality of life helper so instead of using: rcu_replace_pointer(rp, p, lockdep_rtnl_is_held()) .. or the open coded.. rtnl_dereference() / rcu_assign_pointer() .. or the lazy check version .. rcu_replace_pointer(rp, p, 1) Use: rcu_replace_pointer_rtnl(rp, p) Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: Victor Nogueira <victor@mojatatu.com> Signed-off-by: Pedro Tammela <pctammela@mojatatu.com> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.

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.
