New Revision: 223786
URL: http://svn.freebsd.org/changeset/base/223786
Log:
Only print entries for which ut_host points to a character device.
Now that we use utmpx, we more often have entries for which the ut_line
is left blank. To prevent us from returning struct stat for "/dev/",
check that the resulting stat structure belongs to a character device.
