svn commit: r262727 - head/sys/net

[George V. Neville-Neil]

Author: gnn
Date: Tue Mar  4 05:09:46 2014
New Revision: 262727
URL: http://svnweb.freebsd.org/changeset/base/262727

Log:
  Naming consistency fix. The routing code defines
  RADIX_NODE_HEAD_LOCK as grabbing the write lock,
  but RADIX_NODE_HEAD_LOCK_ASSERT as checking the read lock.
