"An update of the stale smp_call_function_many() documentation to bring
it back in sync with the actual implementation"

* @mask: The set of cpus to run on (only runs on online subset).
885
885
* @func: The function to run. This must be fast and non-blocking.
886
886
* @info: An arbitrary pointer to pass to the function.
887
-
* @wait: Bitmask that controls the operation. If %SCF_WAIT is set, wait
888
-
* (atomically) until function has completed on other CPUs. If
889
-
* %SCF_RUN_LOCAL is set, the function will also be run locally
890
-
* if the local CPU is set in the @cpumask.

892
-
* If @wait is true, then returns once @func has returned.

* @wait: If true, wait (atomically) until function has completed
888

* You must not call this function with disabled interrupts or from a
895
891
* hardware interrupt handler or from a bottom half handler. Preemption
896
892
* must be disabled when calling this function.
893

*
894
+
* @func is not called on the local CPU even if @mask contains it. Consider
895
+
* using on_each_cpu_cond_mask() instead if this is not desirable.
