* btree: export btree_get_prev() so modules can use btree_for_eachSteve Hodgson2012-01-101-0/+1
| | | | | | | | | | | | | | The btree_for_each API is implemented with macros that internally call btree_get_prev(), so if btree_get_prev() isn't exported then modules fail to link if they try to use one of the btree_for_each macros. Since the rest of the btree API is exported, we should keep things orthogonal and make this work too.
