I was wondering if the first patch in this series: [PATCH V3 1/6] mm: Introduce a general RCU get_user_pages_fast. http://marc.info/?l=linux-mm&m=140923713202355&w=2 could be merged into 3.18 via an mm tree, or if there are any issues with the patch that I should fix? Acks or flames from the mm maintainers would be greatly appreciated! Cheers, -- Steve -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
