New Revision: 211732
URL: http://svn.freebsd.org/changeset/base/211732
Log:
- According to specification, SI_USER code should only be generated by
standard kill(). On other systems, SI_LWP is generated by lwp_kill().
This will allow conforming applications to differentiate between
signals generated by standard events and those generated by other
implementation events in a manner compatible with existing practice.
- Bump __FreeBSD_version
