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.
v4
Mark the '_rcu_read_auto_' variable as 'unused'
to work around a clang bug.
Dr. David Alan Gilbert (5):
rcu: Add automatically released rcu_read_lock variants
migration: Fix missing rcu_read_unlock
migration: Use automatic rcu_read unlock in ram.c
migration: Use automatic rcu_read unlock in rdma.c
rcu: Use automatic rc_read unlock in core memory/exec code
