kdump (Linux) – Linux kernel's crash dump mechanism, which internally uses kexec System.map – contains mappings between symbol names and their addresses in memory, used to interpret oopses References
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
In computing, a loadable kernel module (LKM) is an object file that contains code to extend the running kernel, or so-called base kernel, of an operating system.LKMs are typically used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls.
EDAC is a Linux kernel subsystem that handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures. EDAC drivers for other architectures like arm also exists. It is recommended to use rasdaemon to gather MCE information on Linux systems because mcelog has been deprecated as of 2017.

On a host with a scanner, the saned daemon runs and handles network requests. On client machines a "net" back end (driver) connects to the remote host to fetch the scanner options, and perform previews and scans. The saned daemon acts as a front end locally, but simply passes requests and data between the network connections and the local scanner.
The Linux API is composed out of the system call interface of the Linux kernel, the GNU C Library (by GNU), libcgroup, [1] libdrm, libalsa and libevdev [2] (by freedesktop.org). Linux API vs. POSIX API. The Linux API includes the kernel–user space API, which allows code in user space to access system resources and services of the Linux kernel ...
