The low-level driver libraries are expected to be fully thread-safe.
Basically the same rules as in Documentation/infiniband/core-locking.txt
for the kernel level.  However I agree that this expectation is not
written down anywhere.  I guess libibverbs needs some documentation
for low-level driver authors.  Not sure where to put it (I don't think
a man page is really appropriate, is it?).
