名称描述
stop_one_cpustop_one_cpu - stop a cpu*@cpu: cpu to stop*@fn: function to execute*@arg: argument to @fn* Execute @fn(@arg) on @cpu. @fn is run in a process context with* the highest priority preempting any task on the cpu and* monopolizing it
stop_two_cpusstop_two_cpus - stops two cpus*@cpu1: the cpu to stop*@cpu2: the other cpu to stop*@fn: function to execute*@arg: argument to @fn* Stops both the current and specified CPU and runs @fn on one of them.* returns when both are completed.
__stop_cpus
stop_machine_from_inactive_cpustop_machine_from_inactive_cpu - stop_machine() from inactive CPU*@fn: the function to run*@data: the data ptr for the @fn()*@cpus: the cpus to run the @fn() on (NULL = any online cpu)* This is identical to stop_machine() but can be called from a CPU which
