Linux Kernel 4.8.9 Adds SunRPC and s390 Improvements, Lots of Updated Drivers

Just four days after the release of Linux kernel 4.8.8, Greg Kroah-Hartman announces on the 19th of November the availability of the ninth maintenance update in the stable series, which currently powers several rolling distributions, including the popular Arch Linux, Solus, and openSUSE Tumbleweed. Linux kernel 4.8.9 is a fairly normal point release that changes a total of 97 files, with 725 insertions and 399 deletions. Looking at the appended shortlog and the diff since Linux kernel 4.8.8, we can notice that Linux kernel 4.8.9 comes with an updated networking stack that includes multiple improvements for the SunRPC remote procedure call protocol, along with some minor Netfilter, B.A.T.M.A.N. Advanced, and Ceph fixes, an workaround to the -Wmaybe-uninitialized warning for NFS v4.1 filesystems, and a few sound stack updates.
