Augustin Cavalier c2cbf95810 kernel: Add and fix ownership checks in mutex_destroy and mutex_transfer.
* mutex_destroy() only checked wether or not there were waiters,
   not if the lock itself was presently held by another thread.
   Now we do, which should make #15015 panic much earlier instead
   of trying to use freed memory.
 * mutex_transfer_lock() and recursive_lock_transfer_lock() did
   not check that the calling thread actually owned the lock.
   Now it does, which should trigger asserts if anyone tries
   to do this.

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!
