69 Walk all nodes associted with the mountpoint
74 The walk is aborted if

84 callback, when cached data for every node should be flushed to stable
86 .It Fn puffs_pn_remove pn
87 Signal that a node has been removed from the file system, but do not
88 yet release resources associated with the node.
89 This will prevent the nodewalk functions from accessing the node.
90 If necessary, this is usually called from
93 .Fn puffs_node_rmdir .
94 .It Fn puffs_pn_put pn
95 Free all resources associated with node
97 This is typically called from
98 .Fn puffs_node_reclaim .
