Re: [PATCH] mm/vmalloc: lock contention optimization under multi-threading

[rulinhuang]

Hi Rezki, we have submitted patch v2 to avoid the partial 
initialization issue of vm's members and separated insert_vmap_area() 
from alloc_vmap_area() so that setup_vmalloc_vm() has no need to 
require lock protection. We have also verified the improvement of 
6.3% at 160 vcpu on intel icelake platform with this patch.
Thank you for your patience.
