Linux Kernel 4.8 RC1 released. Ubuntu users can update Kernel via command line (apt-get). Here’s how to install the latest Linux Kernel on Ubuntu System. Update the Ubuntu mainline Kernel. Linux Kernel v4.8-rc1 is the first Release Candidate for the upcoming Linux 4.8 kernel series. It brings 10787 files changed, 612208 insertions, 272098 deletions and lots of doc updates.
Announcing the Kernel 4.8 RC1 release, Linus Torvalds wrote “If you ignore the documentation format change, things look fairly regular, with about 60% of the non-documentation diffs being drivers (gpu, networking, media, sound, etc) and about 15% being arch updates (arm, powerpc and x86 dominate, but there’s mips and s390 too). The rest is spread out – core networking, tooling (mainly perf), include files, core kernel, vfs and low-level filesystems (xfs stands out). Few areas escaped: 10787 files changed, 612208 insertions(+), 272098 deletions(-).”
