14000 developers from 1300 companies have contributed, since 2005.
From 3.19 to 4.7, an average of 4600 lines of code was added daily.
Over 80% of all kernel development is done by developers paid for their work.
A small number of companies are responsible for a large portion of the total changes. These being, from biggest to lowest contributor: Intel (12.9%), Red Hat (8,0%), Linaro (4%), Samsung, SUSE, IBM, Google (2%), AMD, Texas Instruments, ARM, Oracle.
Contributions from unpaid developers have been in decline for many years. 14.6% in 2012, 7.7% in 2016.
