Hello,
I've been debugging for quite a long time strange issues with encrypted DVDs
not being readable on Linux (bko#194965). In the end I've tracked down the
problem to the fact that block device size is not updated when the media is
inserted in case the DVD device is already open. This is IMO a bug in block
device code as the size gets properly update in case the device has partition
scanning enabled. The following series fixes the problem by refreshing disk
size on each open even for devices with partition scanning disabled.
