[libvirt] [PATCH 0/5] Fix virtlockd loosing locks

This is a workaround for the bizarre behaviour whereby the kernel throws
away all fcntl() locks on execve()... if any threads are running. We
simply make virtlockd & virlogd single threaded instead.

Daniel P. Berrangé (5):
  rpc: push ref acquisition into RPC dispatch function
  rpc: simplify calling convention of virNetServerClientDispatchFunc
  rpc: invoke the message dispatch callback with client unlocked
  rpc: avoid crashing in pre-exec if no workers are present
  rpc: switch virtlockd and virtlogd to use single-threaded dispatch
