[Qemu-block] [PATCH 0/2] coroutine: Assertions and debugging aids

[Kevin Wolf]

A while ago we were debugging a hang where coroutines were waiting for a mutex
to be unlocked, but we couldn't find out who held the lock. This series adds
some information to Coroutine and CoMutex that both allows to add a few
assertions to check locking behaviour and can be used to find the culprit when
analysing a core dump.

  coroutine: Let CoMutex remember who holds it
  coroutine: Assert that no locks are held on termination
