v2->v3: - Move the rbtree linking operation from dso__set_long_name() to dsos__add(), where the list_add() operation was done. - Add a second patch to remove the linked list and iterates the DSO structures by going through them in the rbtree. This requires changes in quite a number of files, but it makes for neater code. - Rebased to the 3.17-rc5 kernel.
v1->v2: - Rename DSO longname RBtree find function to segregate its two different uses of searching and linking DSO into RB tree.
This patch set replaces the list that is linking the DSO structures of the perf tool by rbtree sorted by its long name. This can significantly speed up DSO processing when a large number of DSOs are beining profiled.
