Can we just delay this > one commit until after bcachefs has been converted (and any other > references that may be added are fixed)? Yeah, I guess removing the final commit is the easiest solution at this point. It complicates a bit the series to disallow writing to mounted block devices which bases on this - either I have to pospone that to the next cycle after we convert bcachefs or I have to find a way for the old blkdev_get_by_path() API and the new functionality to coexist. I'll think about that. Honza -- Jan Kara SUSE Labs, CR
