No longer hold RTNL while calling ip6addrlbl_dump()
("ip addrlabel show")
ip6addrlbl_dump() was already mostly relying on RCU anyway.
Add READ_ONCE()/WRITE_ONCE() annotations around
net->ipv6.ip6addrlbl_table.seq
Note that ifal_seq value is currently ignored in iproute2,
and a bit weak.
We might user later cb->seq / nl_dump_check_consistent()
protocol if needed.
Also change return value for a completed dump,
so that NLMSG_DONE can be appended to current skb,
saving one recvmsg() system call.
v2: read net->ipv6.ip6addrlbl_table.seq once, (David Ahern)

README
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.
