New Revision: 191118
URL: http://svn.freebsd.org/changeset/base/191118
Log:
Remove dead code from devtoname().
In the good old days it was possible to have dev_t's that referred to
nonexistent devices. In these cases devtoname() automatically generated
names. This is no longer possible, so remove this dead code.
