The 4.18 kernel is out

Linus has released the 4.18 kernel.
It was a very calm week, and arguably I could just have released on
schedule last week, but we did have some minor updates.

Some of the significant features in this release include
unprivileged filesystem mounts,
restartable sequences,
a new zero-copy TCP receive API,
support for active state management for
power domains,
the AF_XDP mechanism for
high-performance networking,
the core bpfilter packet filter
implementation,
and more. See the KernelNewbies 4.18 page for
more details.
