SubjectDo we need to disable preemption in flush_tlb_range()?
Date
Hi Vineet,

Just noticed that in comments for smp_call_function_many() it is said that
preemption must be disabled during its execution. And that function gets executed
among other ways like that:
-------------------------->8-----------------------
flush_tlb_range()
-> on_each_cpu_mask()
-> smp_call_function_many()
-------------------------->8-----------------------

I'm not seeing right now any real problem with current implementation but
some architectures do that thus the question.
