Rename MovePageRange to Adopt and group it with Resize/Rebase as it covers the third, middle cut case. Implement VMAnonymousCache::Adopt() to actually adopt swap pages. This has to recreate swap blocks instead of taking them over from the source cache as the cut offset or base offset between the caches may not be swap block aligned. This means that adoption may fail due to memory shortage in allocating the swap blocks. For the middle cut case it is therefore now possible to have the adopt fail in which case the previous cache restore logic is applied. Since the readoption of the pages from the second cache can fail for the same reason, there is a slight chance that we can't restore and lose pages. For now, just panic in such a case and add a TODO to free memory and retry.

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!
