Unexpected blkif status disconnected

Unexpected blkif status disconnected

[Niraj Tolia]

I was playing with suspending and resuming Xen domains. Suspend and
restore seems to work. However, when I reconnected with 'xm console',
I got the following error message on screen. Should I be concerned?

[root@ROUGE xen]# xm console FedoraCore2
************ REMOTE CONSOLE: CTRL-] TO QUIT ********
xen_blk:  Unexpected blkif status disconnected in state connected
blkfront: recovered 0 descriptors
                                  
Thanks,
Niraj

Nothing bad has happened, it's just being chatty.

We should probably quieten it down, but somehow I find it
reassuring whenever I see the message. I guess I just spent too
long trying to find a bug in that code back in May :-)

[If you're running with restartable device drivers domains then
the above message would effectively be telling you that the
driver domain rebooted and client has reconnected. ]

I recently changes those messages to DPRINTK's so non-debug builds
will no longer scare users. ;-)
