Author: davide Date: Sun Sep 1 23:34:53 2013 New Revision: 255138 URL: http://svnweb.freebsd.org/changeset/base/255138 Log: Fix socket buffer timeouts precision using the new sbintime_t KPI instead of relying on the tvtohz() workaround. The latter has been introduced lately by jhb@ (r254699) in order to have a fix that can be backported to STABLE.
