Tao Chen f059795ec6 bpf: Remove migrate_disable in kprobe_multi_link_prog_run ... [ Upstream commit abdaf49be5424db74e19d167c10d7dad79a0efc2 ] Graph tracer framework ensures we won't migrate, kprobe_multi_link_prog_run called all the way from graph tracer, which disables preemption in function_graph_enter_regs, as Jiri and Yonghong suggested, there is no need to use migrate_disable. As a result, some overhead may will be reduced. And add cant_sleep check for __this_cpu_inc_return.
