when a FLOSS project gets real big


Serious scale:

Developers typically send their changes to the maintainer of the file that is being changed. Those maintainers, who number around 700, feed those changes up to the 130 subsystem maintainers. From there, the patches make their way into linux-next, then to Linus Torvalds, and, eventually the mainline --- if they get accepted at each step along the way.
