The kernel community has a number of excuses for the relative paucity of
regression-test coverage in the project, some of which hold more water than
others. One of the more convincing reasons is that a great deal of kernel
code is hardware-specific, and nobody can ever hope to put together a
testing system with even a small fraction of all the hardware that the
kernel supports. A new driver-testing framework called roadtest,
posted by Vincent Whitchurch, may make that excuse harder to sustain,
though, at least for certain kinds of hardware.
