Augustin Cavalier d00cb444a6 kernel/vm: Decommit discarded pages of overcommitted caches.
Overcommitted caches should only have commitments equal to the
number of pages they actually contain, so we should decommit
whenever pages are discarded.

This changes the API of VMCache::Discard to return an ssize_t
of the size of pages that were discarded (or a negative error on
failure.) Nothing checked the return value besides things in VMCache
itself, it appears; but it apparently never fails, so that's fine.

Also add asserts to Commit() that the new commitment at least
encompasses all pages the cache actually contains.

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!
