## Initializing The Library
The bdev layer depends on the generic message passing infrastructure
abstracted by the header file include/io_channel.h. See @ref concurrency for a
abstracted by the header file include/spdk/thread.h. See @ref concurrency for a
full description. Most importantly, calls into the bdev library may only be
made from threads that have been allocated with SPDK by calling
spdk_allocate_thread().
