What the Linux Staging tree is: The Linux Staging tree (or just “staging” from now on) is used to hold stand-alone drivers and filesystems that are not ready to be merged into the main portion of the Linux kernel tree at this point in time for various technical reasons.
What are staging drivers?
Driver staging is performed under the LocalSystem security context. Adding driver packages to the driver store requires administrative privileges on the system. During driver staging, driver files are verified, copied to the store, and indexed for quick retrieval, but they are not installed on the system.
How does Linux kernel development work?
The kernel source tree contains the drivers/staging/ directory, where many sub-directories for drivers or filesystems that are on their way to being added to the kernel tree live. They remain in drivers/staging while they still need more work; once complete, they can be moved into the kernel proper.
What is the development cycle for Linux?
So, the whole development cycle is a matter of around 10–12 weeks and we get a new version in every three months.
Who manages the Linux kernel?
Greg Kroah-Hartman is among a distinguished group of software developers who maintain Linux at the kernel level. In his role as a Linux Foundation Fellow, he continues his work as the maintainer for the Linux stable kernel branch and a variety of subsystems while working in a fully neutral environment.
What is Linux next kernel?
The linux-next tree is the holding area for patches aimed at the next kernel merge window. If you’re doing bleeding edge kernel development, you may want to work from that tree rather than Linus Torvalds’ mainline tree.
Is Linux a kernel or OS?
Linux, in its nature, is not an operating system; it’s a Kernel. The Kernel is part of the operating system – And the most crucial. For it to be an OS, it is supplied with GNU software and other additions giving us the name GNU/Linux. Linus Torvalds made Linux open source in 1992, one year after it’s creation.
