The possible insertion range for B_*_ANY_ADDRESS always encompasses the entire address space. Even though the initial starting point is now looked up using a binary search tree, actually finding a free spot was then still done using a linear search from there. Store a simple insertion hint, the address directly following the previous insertion of the same type, and use that as the next starting point. In the common case this reduces the needed iterations to zero or near zero. No hint is used for B_*_BASE_ADDRESS specs as it is assumed that the given base address already serves as such a hint. Fixes the area creation performance part of #15995.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
