Do you have a better sulution to this problem?
A bew block layer API that bypasses bio_list maybe? I.e. export
__submit_bio with a better name and a kerneldoc detailing the narrow
use case.
That won't work as we'd miss a lot of checks, cgroup handling, etc.
But maybe a flag to skip the recursion avoidance?
I think this can work, and this can also improve performance. I'll look
into this.
Thanks,
