Michael Lotz 943383c889 DMAResource: Remove incorrect early unlock.
When bounce buffers were changed from fixed to dynamic in hrev27185, the
early unlock in case of physical vectors was not removed. This would
lead to an unprotected fBounceBuffers list and the possibility for
multiple operations to share the same bounce buffer vecs, leading to
disk corruption. This would not happen when used purely under the
IOScheduler as all translations are done from a single thread there.
With the nvme_disk driver that runs requests in parallel, this was
however easy to trigger.

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!
