How to Decide the Linux Kernel Version
summary
Kernel source grows ~1.4% per release or about 200k lines per release with releases every ~60–80 days and 3.8 at 16.4M LOC and 41k files, so production kernels quickly diverge and require constant backports. LTSI (established 2011) provides an industry-managed 2-year kernel that cherry-picks upstream LTS plus extra patches, automatically absorbs security and bug fixes, and offers workshops, mailing lists and patch review to help port in-house changes and upstream them, reducing maintenance and patch-porting cost.
