[Qemu-devel] [PATCH for-2.4 0/2] AioContext: fix deadlock after aio_cont

From: Stefan Hajnoczi
Subject: [Qemu-devel] [PATCH for-2.4 0/2] AioContext: fix deadlock after aio_context_acquire() race
Date: Mon, 27 Jul 2015 17:33:37 +0100

See Patch 2 for details on the deadlock after two aio_context_acquire() calls
race.  This caused dataplane to hang on startup.

Patch 1 is a memory leak fix for AioContext that's needed by Patch 2.

Stefan Hajnoczi (2):
  AioContext: avoid leaking BHs on cleanup
  AioContext: force event loop iteration using BH
