Hi Pekka --

It looks like the build/configuration how-to at
https://oss.oracle.com/projects/tmem/dist/files/RAMster/HOWTO-v5-120214 
is out-of-date and I need to fix some things in it.  I'll post
a link to it after I update it.

Ramster is built on top of kernel sockets.  Both that networking
part and the configuration part of the ramster code are heavily
leveraged from ocfs2 and I suspect there is a lot of similarity
to gfs code as well.  In the code for both of those filesystems
I think the network and configuration code lives in the same
directory with the file system, so that was the model I was following.

I'm OK with placing it wherever kernel developers want to put
it, as long as the reason is not NIMBY-ness. [1]  My preference
is to keep all the parts together, at least for the review phase,
but if there is a consensus that it belongs someplace else,
I will be happy to move it.
