Can we set sectorsize to any number greater than pagesize

Hi, everyone!

mkfs.btrfs just does the following check for sectorsize when we use it to make a btrfs.
sectorsize = max(sectorsize, (u32)getpagesize());

Does that mean we can set sectorsize to any number greater than pagesize? If not, I think we should do more check for sectorsize in mkfs.btrfs.
