Subject: [PATCH] btrfs-progs: mkfs: use correct size for superblock csum and
writeout
If sectorsize is not BTRFS_SUPER_INFO_SIZE (4k), the superblock checksum
is wrong and mkfs fails. This has been reported on ppc64 where we pick
sectorisize from page size (64k). This has been broken since ages
(2008) and discovered by the recently added superblock checks.
