Is the comment here wrong, or do I misunderstand that there is a 64-bit offset for the file, and only a 32-bit offset for the disk? It doesn't make sense to create a new API that only has a 32-bit offset for the disk, since ext4 is nearly supporting 64-bit filesystem blocks.
Oops! Thank you for letting me know. I will fix the comments as follows:
struct ext4_prealloc_info {
__u64 pi_pstart; /* physical offset for the start of the PA from
* the beginning of the disk (in/out) */
__u32 pi_lstart; /* logical offset for the start of the PA from
* the beginning of the file (in/out) */
