Hi Valdis --

Thanks for your reply!

Per the discussion at:
https://lkml.org/lkml/2011/12/22/369 
your suggestion of the common subdirectory will definitely need to happen
before ramster can be promoted out of staging and, at GregKH's request,
I have added a TODO file in V3 to state that.  Before that can happen,
we'll need to work with the ocfs2 maintainers to merge the
necessary ramster-specific changes and implement a separately CONFIG-able
subdirectory for the ocfs2 cluster code.
