Author: julian Date: Fri Mar 18 14:49:11 2016 New Revision: 297023 URL: https://svnweb.freebsd.org/changeset/base/297023 Log: Add the ability to print out ht emodule specific information in likely formats. Among other things this gives us the ability to find outthe syscall number of a dynamically loaded syscall that has a dynamicly allocated vector number. MFC after: 1 week Sponsored by: Panzura inc.
