Is it allowed to connect to a nvme in one thread (spdk_nvme_connect) and
use the controller handle returned in different threads to allocate and use
qpairs (spdk_nvme_ctrlr_alloc_io_qpair)? Or does everything have to be done
in a single thread? I'm seeing intermittent buffer corruption and I'm
wondering if this could be the cause?
Thanks,
Trevor

You are allowed to use a controller handle to create to create qpairs on different
threads. The only requirement is that an
individual io_qpair may only be used from a single thread - both submission and processing
completions.
