rcu: Remove stale comment in tree.c
This commit removes a stale comment in rcu/tree.c which was left out when some code was moved around previously in commit 2036d94a7b61 ("rcu: Rework detection of use of RCU by offline CPUs") For reference, the following updated comment exists a few lines below this which means the same: /* Remove the outgoing CPU from the masks in the rcu_node hierarchy. */ Signed-off-by: Pranith Kumar <bobby.prani@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Reviewed-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
