kpatch is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kpatch aims to maximize the system uptime and availability.
This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade. [3] Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
The patch is compiled as usual, but the generated code has additional information about all changed code pieces caused by original source code modification and information on to how to apply these code pieces. The resulting code modifications are safely applied to the running kernel. A special KernelCare kernel module applies the patches. It ...

Ubuntu releases are also given code names, using an adjective and an animal with the same first letter – an alliteration, e.g., "Dapper Drake".With the exception of the first two releases, code names are in alphabetical order, and except for the first three releases, the first letters are sequential, allowing a quick determination of which release is newer.
The Linux kernel is a free and open source, [11]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
Uses the illumos kernel, which is a derivative of OS/Net, which is basically an OpenSolaris/Solaris kernel with the bulk of the drivers, core libraries, and basic utilities. Nexenta OS, based on the illumos kernel with Ubuntu packages; SmartOS, an illumos distribution for cloud computing with Kernel-based Virtual Machine integration.
