[Qemu-devel] [PATCH v2 0/2] make AioContext's bh re-entrant

[Liu Ping Fan]

When trying out of QBL, we badly require more fine defined barrier and atomic 
ops, so
I repost Paolo's atomic patch which fetched github.com/bonzini/qemu.git rcu
(thanks Paolo, with your urcu patches, things go more easily)


v1->v2:
  more fine document
  introduce another wmb for qemu_bh_schedule and correspoing rmb
