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. 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, which is the "

notes: The LKML functions as the central place where Linux developers around the world share patches, argue about implementation details, and discuss other issues. The official releases of the Linux kernel are indicated by an email to LKML. New features are discussed and most code is posted to the list before any action is taken. 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. Author

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. Authors of books such as ''The Linux Kernel Development As A Model of Open Source Knowledge Creation'' and ''Motivation of Software Developers in Open Source Projects'', and ''Recovering Device Drivers'' have made use of LKML for their research studies and surveys.

Calling himself a "really unpleasant person", he later explained "I'd like to be a nice person and curse less and encourage people to grow rather than telling them they are idiots. I'm sorryI tried, it's just not in me." His attitude, which Torvalds considers necessary for making his point clear, has drawn opposition from
