It all looks quite nice, thanks. Couple of things...
You've presumably run a kernel with these various things enabled. What happens? Does the kernel run really slowly? Does userspace collapse in a heap? Does it oops and die?
Also, one place where this infrastructure could be of benefit is in device drivers: simulate a bad sector on the disk, a pulled cable, a timeout reading from a status register, etc. If that works well and is useful then I can see us encouraging driver developers to wire up fault-injection in the major drivers.
Hence it would be useful at some stage to go in and to actually do all this for a particular driver. As an example implementation for others to emulate and as a test for the fault-injection infrastructure itself - we may discover that new capabilities are needed as this work is done.
I wouldn't say this is an urgent thing to be doing, but it is a logical next step..
