We've got releasepage, invalidatepage, and now release, all with slightly different semantics and some complex interactions with the rest of the VM. One problem I have with the btrfs extent state code is that I might choose to release the extent state in releasepage, but the VM might not choose to free the page. So I've got an up to date page without any of the rest of my state. Which of these ops covers that? ;) I'd love to help better document the requirements for these callbacks, I find it confusing every time. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
