From: Albert van der Linde <alinde@xxxxxxxxxx> The goal of this series is to improve testing of fault-tolerance in usages of user memory access functions, by adding support for fault injection. The first patch adds failure injection capability for usercopy functions. The second changes usercopy functions to use this new failure capability (copy_from_user, ...). The third patch adds get/put/clear_user failures to x86.
