This patch uses glib's g_auto mechanism to automatically free
rcu_read_lock's at the end of the block.  Given that humans
have a habit of forgetting an error path somewhere it's
best to leave it to the compiler.

In particular:
suggests we've forgotten an unlock case somewhere in the
rdma migration code.


Dr. David Alan Gilbert (3):
  rcu: Add automatically released rcu_read_lock variant
  migration: Use automatic rcu_read unlock in ram.c
  migration: Use automatic rcu_read unlock in rdma.c
