Why: Implementation became generic; users should now include
linux/semaphore.h instead.
Who: Matthew Wilcox <willy@linux.intel.com>
+
+---------------------------
+
+What: SCTP_GET_PEER_ADDRS_NUM_OLD, SCTP_GET_PEER_ADDRS_OLD,
+ SCTP_GET_LOCAL_ADDRS_NUM_OLD, SCTP_GET_LOCAL_ADDRS_OLD
+When: June 2009
+Why: A newer version of the options have been introduced in 2005 that
+ removes the limitions of the old API. The sctp library has been
+ converted to use these new options at the same time. Any user
+ space app that directly uses the old options should convert to using
+ the new options.
