Fixit clarification:

This would involve a new OfflinePageBridge function that has a signature:

OfflinePageBridge#selectPagesForOnlineUrls(
   List<String> urls,
   Callback<List<OfflinePageItem>> result)

The pages could be found by querying the offline page model for all pages that match the set of URLs, and then picking the best page for each URL.  Note that this API will not support pages that are restricted to a particular tab, but it appears that the NTP section using this API will not need those pages.

AFAIK, we (NTP) are not using selectPageForOnlineUrl explicitly anymore. I am not sure what we do now. However, I still believe that the batch version could be of use.

Is this obsolete code or still using it?

Ok, we are still using the function.
I just searched badly and missed it, sorry for misleading you.

So here https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chrome/browser/suggestions/SuggestionsOfflineModelObserver.java?q=selectPageForOnlineUrl+file:%5Esrc/chrome/android/java/src/org/chromium/chrome/browser/suggestions/+package:%5Echromium$&l=65 we could use a batch version of the selectPageForOnlineUrl function.
