Florian Westphal 4e645b47c4 netfilter: core: make nf_unregister_net_hooks simple wrapper again
This reverts commit d3ad2c17b4
("netfilter: core: batch nf_unregister_net_hooks synchronize_net calls").

Nothing wrong with it.  However, followup patch will delay freeing of hooks
with call_rcu, so all synchronize_net() calls become obsolete and there
is no need anymore for this batching.

This revert causes a temporary performance degradation when destroying
network namespace, but its resolved with the upcoming call_rcu conversion.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
