Hi ,
If we call submit_bio/blk_execute_rq and due to some target issues we hit
the blk_rq_timed_out.

In blk_rq_timed_out=C2=A0=C2=A0 =C2=A0__blk_complete_request =C2=A0gets cal=
led only in
BLK_EH_HANDLED case and if q->rq_timed_out_fn doesn=E2=80=99t return
BLK_EH_HANDLED
and returns only BLK_EH_NOT_HANDLED/ BLK_EH_RESET_TIMER.

How will the submit_bio/blk_execute_rq returns from it wait state ?
Will we see the hungtask in this case?

Any help regarding this will help me a lot .

Regards,
Muneendra.
