- Keep track of file name to avoid lookups when we can. This makes sure we do not have two cookies for the same inode, a situation that cause wreak havoc when we come to remove or rename a node. - Do not use PUFFS_FLAG_BUILDPATH at all, since we now track file names - In open, queue requests after checking for access, as there is no merit to queue a will-be-denied request while we can deny it immediatly - request reclaim of removed nodes at inactive stage
