Inject zinject(8) a percentage amount of dev errs
In the original form of device error injection, it was an all or nothing
situation. To help simulate intermittent error conditions, you can now
specify a real number percentage value. This is also very useful for our
ZFS fault diagnosis testing and for injecting intermittent errors during
load testing.
