We'd also need to reject this when reading partitions from disk, right? > + /* check if partition is aligned to blocksize */ > + if (p.start % bdev_physical_block_size(bdev) != 0) And this should be bdev_logical_block_size, as the logical block size is the only thing that matters for the OS - exposing the physical block size is just an optional hint to prevent users from doing stupid things (like creating unaligned partitions :))
