Spdk notes

// TODO: Need to handle spdk_bs_opts_init and spdk_bs_load // It is used to read the initial set of blobs: that's what's used by blob_fs // to build the initial tree of files. // spdk_blob_set_xattr can be used for storing attributes, like file name. // spdk_blob_remove_xattr, // spdk_blob_get_xattr_value, // spdk_blob_get_xattr_names

// TODO: Most functions can only be called on the initial thread, including // the initial load. Therefore, once we allow multithreading, we need to send // messages to that thread for execution and get back responses.
