read_lock( & tasklist_lock)

637

Careful: this is a double loop, 'break' won't work as expected. (g, task)

638

Switch the patched state of the task to the set of functions in the target* patch state.* NOTE: If task is not 'current', the caller must ensure the task is inactive.* Otherwise klp_ftrace_handler() might read the wrong 'patch_state' value.

read_unlock( & tasklist_lock)

641

for_each_possible_cpu(cpu)

642

Switch the patched state of the task to the set of functions in the target* patch state.* NOTE: If task is not 'current', the caller must ensure the task is inactive.* Otherwise klp_ftrace_handler() might read the wrong 'patch_state' value.
