Unfortunately, I have no idea better than you suggested. :(

And looking 8891d6da17, mlock's lru_add_drain_all isn't must.

"grep lru_add_drain_all mm/*.c".  They're all problematic.

Yeb but I'm not sure such system modeling is good.
Potentially, It could make problem once we use workqueue of other CPU.
