Hi Doug,

This patch set refactors RDMA IOCTL declarations, unifies their
location, moves all current IOCTL exporters to one place and renames
them to fix the differences in coding style.

IOCTLs commands need to export the size of their data for their transfer
which is usually declared as a struct defined in relevant submodule.
These structures should be visible at the linkage stage.

Just for my understanding - this is not an issue only with RDMA-IOCTLs,
right?
(Wondering how other modules approaches this).

I'm not familiar with all subsystems, but IMHO, we will find all
possible solutions. While working on the patches, I took a look on
other subsystems and they exposed structures in the same file
as IOCTLs from the day one.
