"In a long and meandering thread with some of the other kernel
developers a week or so ago, it came up that there is no single
place for companies and developers to put their code for testing
while it gets cleaned up for submission into the kernel tree. All
of the different subsystems have trees, but they generally only
want code that is about to go into this release, or the next one.
For stuff that is farther off, there is no place to go.
