For pages that were retained via get_user_pages*(), release those pages via the new put_user_page*() routines, instead of via put_page() or release_pages().
This is part a tree-wide conversion, as described in commit fc1d8e7cca2d ("mm: introduce put_user_page*(), placeholder versions").
This also handles pages[i] == NULL cases, thanks to an approach that is actually written by Juergen Gross.

Hi Juergen,
Say, this is *exactly* what you proposed in your gup.patch, so I've speculatively added your Signed-off-by above, but need your approval before that's final. Let me know please...
Yes, that's fine with me.
