[ Upstream commit5df1341ea8] hlist_for_each_entry_rcu() has built-in RCU and lock checking. Pass cond argument to hlist_for_each_entry_rcu() to silence false lockdep warning when CONFIG_PROVE_RCU_LIST is enabled. Execute as follow: ip link add link eth0 type macvlan mode source macaddr add <MAC-ADDR> The rtnl_lock is held when macvlan_hash_lookup_source() or macvlan_fill_info_macaddr() are called in the non-RCU read side section. So, pass lockdep_rtnl_is_held() to silence false lockdep warning. Fixes:79cf79abce("macvlan: add source mode") Signed-off-by: Chuang Wang <nashuiliang@gmail.com> 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.
