Some more information on "before adding something new in" - the new flag as a
reference but not yet posted anywhere...

https://github.com/xzpeter/linux/commit/102790511a1a25b7be841fb2059a8c8d8f1a87b2

I still think this small series worths to be reviewed/merged even before that
new flag, because patch 1 should definitely be something good to have, patch 2
prepares for patch 3 and the new bit (which can be seen as optional), but patch
3 should help make things clearer rather than using non-null "details" pointer
to show "whether we should skip swap entries", which can be easily misused IMHO
when someone accidentally replaced one "details==NULL" with some valid pointer.

Of course I can repost these series with the larger one when time comes too,
but I'd still like to at least get a NO early if there is...

Thanks,
