OK.  Fair enough.  That implies to me that you probably dove right into
the patches and skimmed the cover letter (http://marc.info/?l=linux-s39
0&m=148397751211964&w=2), because when I read the cover letter, it
seems pretty clear to me that this is very much RDMA related.  In any
case, there are already two other code bases that live under net/ but
also involve RDMA heavily: nfs and rds.  This is a third now.  So, for
future reference, just like the RDMA related nfs/rds patches already
get Cc:ed to linux-rdma@, these probably should be too.

I'm glad to hear that.  I wish we had managed to get together on this
sooner.
