Florian Westphal 5e4d107abd netfilter: nf_conntrack: speed up reads from nf_conntrack proc file 
Dumping all conntrack entries via proc interface can take hours due to
linear search to skip entries dumped so far in each cycle.

Apply same strategy used to speed up ipvs proc reading done in
commit 178883fd03 ("ipvs: speed up reads from ip_vs_conn proc file")
to nf_conntrack.

Note that the ctnetlink interface doesn't suffer from this problem, but
many scripts depend on the nf_conntrack proc interface.

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.
