Stale cached data in bdbuf creates problems

[Sebastian Huber]

Hi,

I will use this notation dev = (major, minor).  First you create a 
driver and get a major number.  The physical disk will be (major, 0).  
Now you call rtems_bdpart_register() and this will create logical disks 
(major, X) with X = 1, ..., partition count.  You have to sync and purge 
all disks (major, 0), ..., (major, partition count).  The media manager 
takes care of this, maybe it make sense to port it to 4.10.
