Hi, Shakeel,

I saw your v2 has started to pass in zap_details, then we need know the side
effect on that skip-swap-entry thing because with your v2 code munmap() will
start to skip swap entry too (while it was not before).

I saw that you didn't mention this in v2 patch either in commit message or
code, not sure whether you digged that up.  I think it needs some double check
(or feel free to start this digging by reviewing my small patch above :).
I remember mentioning in the patch that this has dependency on your
rfc patch. Just checked again and yeah I only mentioned in the
'changes since v1' section. I will add it more explicitly in the
following versions.
Apologize for missing that section.  Yeah depending on that patch should work.
I will take a close look at your patch as well.
Thanks a lot,
