[openib-general] Loading / unloading IB modules

Fri Mar 26 14:56:37 PST 2004

Amount of code is not so much the issue.

Linux modules are truly goodness, although they can be easily abused.
The shear number of modules required, leads me to question the overall
architecture design?

What is the advantage of having so many modules?

You ask what is the disadvantage of have numerous modules? Time spent
loading, unloading, debug. In the bigger picture having a large number
of modules not a huge issue, but it does beg the question of over all
design.

Are you concerned about the number of modules or the amount of code?

The number of modules could easily be reduced by combining some, but I
don't see why that would be a big concern.
