Author: dchagin Date: Sun Apr 2 07:46:13 2017 New Revision: 316393 URL: https://svnweb.freebsd.org/changeset/base/316393
Log: As noted by bde@ negative tv_sec values are not checked for overflow, so overflow can still occur. Fix that. Also remove the extra check for tv_sec size as under COMPAT_LINUX32 it is always true.
