====================
ipv6: Drop RTNL from mcast.c and anycast.c
This is a prep series for RCU conversion of RTM_NEWNEIGH, which needs
RTNL during neigh_table.{pconstructor,pdestructor}() touching IPv6
multicast code.
Currently, IPv6 multicast code is protected by lock_sock() and
inet6_dev->mc_lock, and RTNL is not actually needed.
In addition, anycast code is also in the same situation and does not
need RTNL at all.
This series removes RTNL from net/ipv6/{mcast.c,anycast.c} and finally
removes setsockopt_needs_rtnl() from do_ipv6_setsockopt().

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 reStructuredText 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.
