This is very similar to sx_init_flags: it initializes the rwlock using special flags passed as third argument (RW_DUPOK, RW_NOPROFILE, RW_NOWITNESS, RW_QUIET, RW_RECURSE). Among these, the most important new feature is probabilly that rwlocks can be acquired recursively now (for both shared and exclusive paths). Because of the recursion counter, the ABI is changed.
