SubjectRe: [PATCH 2.6.20-rc1] ib_verbs: Use explicit if-else statements to avoid errors with do-while macros
I see Linus already took this, which is fine... blame me for merging
this without fixing my cross-compile testbed.

This stuff wasn't needed, was it? It's only the wrappers around void
functions that can't use ?: I would think... surely any trivial macro
replacement for a dma API function that returns a value must evaluate
to something like (0) that is safe to use in this context.
