handlerinput handler to iterate
datadata for the callback
fnfunction to be called for each handle
Iterate over bus's list of devices, and call fn for each, passing
it data and stop when fn returns a non-zero value. The function is
using RCU to traverse the list and therefore may be usind in atonic
contexts. The fn callback is invoked from RCU critical section and
thus must not sleep.
