Hi, Paolo,
Did you test this? bio_split calls bio_clone_bioset or bio_clone_fast,
so I'd be surprised if you didn't trigger that newly added warning. :-)
Of course I didn't check the kernel log ...
I hope next version will not introduce more bugs than it will fix.
Thanks,
Paolo
Please remove the bio_split call site.
Cheers,
Jeff
