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. Thanks, Yoshihiro YUNOMAE -- Yoshihiro YUNOMAE Software Platform Research Dept.

[PATCH 1/3] scsi/trace: Use macros for getting driver byte, host byte, msg byte, and status byte
For getting driver byte, host byte, msg byte, and status byte, macros are implemented in scsi/scsi.h, so we use it. Signed-off-by: Yoshihiro YUNOMAE Reviewed-by: Ewan D.
