The Linux Foundation released the Linux kernel Development Status Report (PDF) for the second consecutive year ). The report tracks the development between kernel 2.6.24 and 2.6.30. The report shows that development of Linux kernel is accelerating.

According to the report, on average 5547 lines of code have been removed every day since kernel 2.6.24, 2243 lines of code have been modified, and 10923 lines have been added. On average, 5.4 patches are added to the tree every hour. Last year's report was 3.83, an increase of 42%, which is far higher than other open-source projects. In the past 4.5 years, a total of 4190 developers donated code. The top 10 developers contributed code to 12% of the total, and the top 30 developers contributed 25%. The number of patches donated by Linus Torvalds has not ranked among the top 30, but his contribution cannot be measured by the number of patches. Linus has donated 254 patches since 2.6.24, bartlomiej zolnierkiewicz donated a maximum of 1,169 patches. Red Hat kernel developer Ingo Molnar donated 1,164 patches, followed by David S. miller (851), Chris Mason (717), Takashi Iwai (711), Adrian bunk (708), Harvey harharrison (669), yinghai Lu (609 ), greg kroah-Harman (608), Paul Mundt (579), Al Viro (550), Alan Cox (545), etc. For the company, Red Hat accounts for 12.3% of the total number of patches, IBM accounts for 7.6%, Novell is 7.6%, Intel is 5.3%, Oracle is 2.4%, Linux foundation is 1.6%, SGI is 1.6%.
