Subject: [PATCH 2/3] 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.
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. */
