Given a collection of numbers, find the longest monotonic prefix (ascending or descending), i.e. l-m-prefix [3 2 1 2 3 4] => [3 2 1].

Simple cardinality estimator. You can provide hash<T> specializations for custom types, as long as the hash values roughly follow a uniform distribution. Otherwise the estimation gets skewed.

ceph/ceph @24c5ea8: -Weverything

A plea for more tooling usage

Motivation

I tried to build Ceph with the Clang (3.4) compiler. The only issue preventing the build to finish was a "VLA of non-POD type" usage which I fixed here:

ceph/ceph#1768
