Replying to my own message.
I assume this is because we have this in kernel:

/*
 * The remap event
 */
struct blk_io_trace_remap {
        __be32 device;
        u32 __pad;
        __be64 sector;
};

but this in blktrace:

/*
 * The remap event
 */
struct blk_io_trace_remap {
        __u32 device;
        __u32 device_from;
        __u64 sector;
};

Correct?
