Hi Jens,

This is a small patch-series which allows zone-mgmt ops to handle
SIGKILL. This patch series formatted on the top of following patch:-
https://marc.info/?l=linux-block&m=157321402002207&w=2.

* Changes from V1:-

1. Export blk_should abort() to avoid code duplication.
2. Reuse blk_should_abort() and return -EINTR when zone-mgmt
   ops is interrupted when last submit_bio_wait() is successful.

In case you want me to add original patch posted by Tetsuo Honda,
I'll be happy to respin this series so we can have everything
in one patch-series.

Regards,
Chaitanya
