However, I think these two are not equal when the > device has 4k logical block size. The former uses Linux kernel sector size 512 > byte. The latter use 512b sector size or 4kb sector size depending on the > device. mkfs.f2fs obtains logical block size via BLKSSZGET ioctl from the device > and reflects it to the value sbi->log_sector_size_per_block.

What do you think?
