Has the linux-kernel already implemented the functions in apollo-kernel?

[Hongyi Zhao]

Hi,

The apollo-kernel (https://github.com/ApolloAuto/apollo-kernel) is a
patched Linux Kernel based on official Linux Kernel 4.4.32 with some
modifications on the kernel level, especially for the scenario
necessary to run the Apollo (https://github.com/ApolloAuto/apollo)
open autonomous driving platform software stack.

According to the official description as shown
<https://github.com/ApolloAuto/apollo-kernel#what-is-the-difference>,
the major difference from the original Linux kernel is as follows:


- Realtime patch (https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO)
- Latest e1000e intel ethernet driver
- Bugfix for Nvidia driver under realtime patch
- Double free in the inet_csk_clone_lock function patch
(https://bugzilla.redhat.com/show_bug.cgi?id=1450972)
- Other cve security patches


However, considering that Linux Kernel 4.4.32 is a fairly old version,
so I want to know whether the modifications/fixes applied/added have
been already available in the current Linux kernel.

Any hints will be highly appreciated.

As you have the source to both trees, why not compare them and see if
all of this is true or not?  That's the best way to be sure.

good luck!
