All my tests with use_blk_mq=n were run with a WARN_ON_ONCE(req->tag <

Bart, what's the data type of "req->tag", here? (E.g., if it
"unsigned", it will never be less than zero, right?)
Hello Webb,
This is what I found in "struct request" in <linux/blkdev.h>:
struct request {
[ ... ]
int tag;
[ ... ]
};
Bart.
