Re: [patch 2/8] fault-injection capabilities infrastructure

[Don Mullis]

Replace individual structure element comments with reference
to Documentation/fault-injection/fault-injection.txt

Init "interval" to 1 (smallest useful value).
Init "times" to 1 rather than -1 (infinity), for fewer 
accidental system lockups.
