Thanks.
To be honest I'm not really happy about it, it's more a short term
bandaid. anon_vma lock and file mapping i_mmap_lock lock are still very hot
in the test, compared to .35. And I didn't find any way to improve
i_mmap_lock.
If someone has better ideas to fix this I would be interested.
Still it's probably a useful short term bandaid.
