Hi GEOM hackers,

I have the following scenario: a mirrored setup with two disks and a 
filesystem on top of it.  Now, if I yank one disk while the fs is not 
mounted, everything works as expected: disk_destroy is called and the 
orphaning events make their way up.

However, if the fs is mounted and I yank the disk, I don't see an 
orphaning event until the fs is unmounted again, so it seems disk_destroy 
is blocked or rather g_wither_geom waits until the device is closed, which 
makes it rather useless in a production area.

Is this the intended behaviour?  pjd@ suggested calling g_destroy_provider 
before g_wither_geom in g_destroy_disk.

cheers,
le
