Hello Martin,

This patch series, when combined with the block layer patch that prevents
that the report and reset zone ioctls are executed while a queue is frozen,
prevents that these ioctls fail sporadically with -EIO. Since this race is
relatively easy to trigger with the SMR support for fio that I'm working on,
please consider this patch series for kernel v4.17.

Thanks,

Bart.
