svn commit: r246796 - user/attilio/vmc-playground/sys/vm

[Attilio Rao]

Author: attilio

New Revision: 246796
URL: http://svnweb.freebsd.org/changeset/base/246796

Log:
  Remove an unuseful check on resident_page_count.
  vm_radix_lookup_ge() of an empty trie is as fast as checking a
  NULL pointer.
