| | | | | | | | | | | | | | | Check if a client passes a NULL callback into an SA query, and if so, never call back. This fixes an oops if someone unloads ib_ipoib and ib_sa in rapid succession. ib_ipoib does an MCMember delete with a NULL callback and 0 timeout on unload, which is usually fine since the delete completes successfully. However, if ib_sa is unloaded immediately afterwards, the delete will be canceled and ib_sa will try to call the (now already unloaded) ib_ipoib module back with the cancel completion, which triggers the oops.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
