NAME
tapset::guru-delay - systemtap guru-delay tapset
DESCRIPTION
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.
mdelay millisecond delay
See function::mdelay(3stap)
for details.
udelay microsecond delay
See function::udelay(3stap)
for details.
