Author: adrian Date: Fri Jan 17 05:13:08 2014 New Revision: 260804 URL: http://svnweb.freebsd.org/changeset/base/260804 Log: Implement the extension api for sendfile to allow for kqueue notifications. This is still under a bit of flux, as the final API hasn't been nailed down. It's also unclear whether we should define the two new types in the header or not - it may allow bad code to compile that shouldn't (ie, since uintX's are defined, the developer may not include sys/types.h.)
