any idea why not map = em->map_lookup; here?
My fault, will update the patch.

Sorry to bother, but looks like this patchset suddenly got forgotten.
It still applies to 4.11 but I'm afraid it won't after 4.12 merge
window. Any update on it?
Just waiting for the flush error rework from Anand Jain.
(Well, I still remember the original patchset has the same thing problem)
Maybe Anand Jain has some idea on this.
Thanks,
Qu
