The Linux kernel mailing list (LKML) is the main electronic mailing list for Linux kernel development,[1][2] where the majority of the announcements, discussions, debates, and flame wars over the kernel take place.[3] Many other mailing lists exist to discuss the different subsystems and ports of the Linux kernel, but LKML is the principal communication channel among Linux kernel developers.[4] It is a very high-volume list, usually receiving about 1,000 messages each day, most of which are kernel code patches.
Linux utilizes a workflow governed by LKML,[5] which is the "bazaar" where kernel development takes place. In his book Linux Kernel Development, Robert Love notes:[3]
If the Linux kernel community had to exist somewhere physically, it would call the Linux Kernel Mailing List home.
The LKML functions as the central place where Linux developers around the world share patches, argue about implementation details, and discuss other issues.[1] The official releases of the Linux kernel are indicated by an email to LKML.[6][7][8] New features are discussed and most code is posted to the list before any action is taken.[3] It is also the official place for reporting bugs in the Linux kernel, in case one cannot find the maintainer to whom the bug should be reported.[9] Author Michelle Delio suggests that it was on LKML that Tux, the official Linux mascot, was suggested and refined,[10] although the accuracy of her reporting in other stories has been disputed.[11] Many companies associated with Linux kernel make announcements and proposals on LKML; for example, Novell,[12]Intel,[13][14]VMware,[15][16] and IBM.[17]
The list subscribers include all the Linux kernel maintainers as well as other known figures in Linux circles, such as Jeff V. Merkey[18] and Eric S. Raymond.[19] A 2000 study found that 14,535 people, from at least 30 countries, sent at least one email to LKML between 1995 and 2000 to participate in the discussion of Linux development.[20]
Authors of books such as The Linux Kernel Development As A Model of Open Source Knowledge Creation[20] and Motivation of Software Developers in Open Source Projects,[21] and Recovering Device Drivers[22] have made use of LKML for their research studies and surveys.
