implemented in scsi/scsi.h, so we use it.
As mentioned about three times in various previous scsi logging discussions
this is entirely wrong and breaks decoding binary trace buffers.
No, this patch uses just macros, so this does not change decoders.
However, other patches change decoders in format files, so we need to
consider about these decoders more, as you say.
We'll discuss on https://lkml.org/lkml/2014/8/28/657.
