Are you aware that there are two tag fields in struct request, namely "tag"
and "internal_tag"? Are you aware that how these fields are used depends on
whether or not a scheduler is attached to a request queue? Have you verified
that the "tag" field contains a meaningful value for blk-mq for every blk-mq
tracepoint?

Thanks,

Bart.
