Hi
I was wondering why namespace_unlock calls synchronize_rcu and not
synchronize_rcu_expedited
Testing shows there is about 20-25 ms saved during an unmount when using
synchronize_rcu_expedited
is there a downside to such a change?
Please let me know.
I would really appreciate any help understanding any pitfalls.
