New Revision: 255870
URL: http://svnweb.freebsd.org/changeset/base/255870
Log:
Re-do r255853. Along with adding back the API/ABI changes from the
original, this hides the contents of cam_compat.h from ktrace/kdump/truss,
avoiding problems there. There are no user-servicable parts in there, so
no need for those tools to be groping around in there.
