tapset::guru-delay - systemtap guru-delay tapset


Functions in the guru-delay tapset allow a probe handler to insert
deliberate delays. This is sometimes useful as a fault-injection
aid. Due to its likelihood of interference with the kernel, guru
mode is required, and overload-prevention is suppressed.
