If I missed to add someone's review tag putting all together - my kind apologise. Please resend it here. I believe I addessed all comments except Joe's one. In comment to patch 3, Joe Perches suggested to rename include/linux/find.h, but didn't give a new name, so I leave it as is. Since this header is not for direct inclusion, I'm OK with any reasonable name, and we can change it later. Andrew, can you please take this series in linux-next?
