rcu: Fix wrong check in list_splice_init_rcu()
If the list to be spliced is empty, then list_splice_init_rcu() has nothing to do. Unfortunately, list_splice_init_rcu() does not check the list to be spliced; it instead checks the list to be spliced into. This results in memory leaks given current usage. This commit therefore fixes the empty-list check. Signed-off-by: Jan H. Schönherr <schnhrr@cs.tu-berlin.de> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
