Not commenting on the rest yet, but I'm sure you noticed that before
your patch we ever called xfs_sync_fsdata with SYNC_WAIT at all.  I
think with the current codebase there is nothing to guarantee we ever
write the superblock out to disk as xfs_wait_buftarg specificly
excludes the superblock (XBF_FS_MANAGED)
