[PATCH tip/core/rcu 10/15] rcu: Remove stale comment in tree.c

From: Paul E. McKenney
Date: Thu Aug 28 2014 - 14:28:52 EST


From: Pranith Kumar <bobby.prani@xxxxxxxxx>

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. */
