["Paul Goyette" <pgoyette%netbsd.org@localhost>]

Module Name:    src
Committed By:   pgoyette
Date:           Sat Jan 14 21:36:59 UTC 2017

Modified Files:
        src/sys/rump/dev/lib/libdrvctl: drvctl_component.c
        src/sys/rump/librump/rumpkern: devsw.c

Log Message:
Don't call the drvctl module's initialization code during rump component
initialization.  Instead, temporarily attach the drvctl's cdevsw to
determine its device c-major, create the /dev/drvctl node using that
c-major, and then detach.  This leaves things in a state where normal
module initialization can run.

Since we're now creating the /dev/drvctl device node correctly, we don't
need to create it again.  So mark the device as DEVNODE_DONTBOTHER in
the devsw_conv0 conversion table.

This bug was introduced more than a year ago (src/sys/kern/kern_drvctl.c
rev 1.40), but was silently ignored except when running a rump_server
built with LOCKDEBUG.
