The Linux kernel also exposes the nomerges sysfs parameter as a scheduler-agnostic configuration, making it possible for the block layer's requests merging logic to be disabled either entirely, or only for more complex merging attempts. [2]
The related system call fsync() commits just the buffered data relating to a specified file descriptor. [1] fdatasync() is also available to write out just the changes made to the data in the file, and not necessarily the file's related metadata. [2] Some Unix systems run a kind of flush or update daemon, which calls the sync function on a ...
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 ...
This article documents the version history of the Linux kernel. Each major version – identified by the first two numbers of a release version – is designated one of the following levels of support: Supported until next stable version; Long-term support (LTS); maintained for a few years [1]
The Linux kernel received a patch for CFS in November 2010 for the 2.6.38 kernel that has made the scheduler "fairer" for use on desktops and workstations. Developed by Mike Galbraith using ideas suggested by Linus Torvalds, the patch implements a feature called auto-grouping that significantly boosts interactive desktop performance. [6]
The Embeddable Linux Kernel Subset (ELKS), formerly known as Linux-8086, is a Linux-like operating system kernel. It is a subset of the Linux kernel , intended for 16-bit computers with limited processor and memory resources such as machines powered by Intel 8086 and compatible microprocessors not supported by 32-bit Linux .
The kerneloops software can collect and submit kernel oopses to a repository such as the www.kerneloops.org website, [7] which provides statistics and public access to reported oopses. A simplified crash screen was introduced in Linux 6.10, similar to the Blue Screen of Death on Windows. [8]
F2FS (Flash-Friendly File System) is a flash file system initially developed by Samsung Electronics for the Linux kernel. [ 5 ] The motive for F2FS was to build a file system that, from the start, takes into account the characteristics of NAND flash memory -based storage devices (such as solid-state disks , eMMC , and SD cards), which are ...
