Errors on net and block drivers - my summary

[Murillo Bernardes <mfb@br.ibm.com>]

Hi

Here is some errors I collected last days on net and block drivers.

1. Frontend directories are not been removed from store on 
{network,block}-detach. Makes xm {network,block}-list show closed devices.

2. Attach a block device after detach that does not work and does not report 
failure - Bug #420.

3. Frontend devices are not been unregistered on {network,block}-detach. 
Causes Bug #420.

4. If a domain die/crash/whatever all backend devices still on dom0.

5. xm {network,block}-{attach,dettach} does not check if operation was 
sucessfull on frontend. (ie. attach more than 3 vif fails, but xm 
network-attach does not report failure)

6. Attach more than 3 vif makes domU kernel OOPS. (probably 
drivers/xen/xenbus/xenbus_probe.c:307-308)

Time to go. Tomorrow I will work on this errors again, and probably file bug 
reports for all of them.

Thanks
