When the node to insert in the rb_tree is known to precede or follow a particular node, new methods RB_INSERT_PREV and RB_INSERT_NEXT, defined here, allow the search for where to insert the new node begin with that particular node, rather than at the root, to save a bit of time. Using those methods, instead of RB_INSERT, in managing a tree in iommu_gas.c, saves a little time. Reviewed by: kib MFC after: 3 weeks Differential Revision: https://reviews.freebsd.org/D35516 |
