Hi Jens,
this series cleans up our main per-device node data structure by merging
the block_device and hd_struct data structures that have the same scope,
but different life times. The main effect (besides removing lots of
code) is that instead of having two device sizes that need complex
synchronization there is just one now.
Note that it depends on the previous "misc cleanups" series.
