rbtree: performance and correctness test
This small module helps measure the performance of rbtree insert and erase. Additionally, we run a few correctness tests to check that the rbtrees have all desired properties: - contains the right number of nodes in the order desired, - never two consecutive red nodes on any path, - all paths to leaf nodes have the same number of black nodes, - root node is black [akpm@linux-foundation.org: fix printk warning: sparc64 cycles_t is unsigned long] Signed-off-by: Michel Lespinasse <walken@google.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Acked-by: David Woodhouse <David.Woodhouse@intel.com> Cc: Rik van Riel <riel@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Daniel Santos <daniel.santos@pobox.com> Cc: Jens Axboe <axboe@kernel.dk> Cc: "Eric W.
