This bug was fixed in head in -r230249:

  Make sure all intermediate variables holding mount flags (mnt_flag)
  and that all internal kernel calls passing mount flags are declared
  as uint64_t so that flags in the top 32-bits are not lost.

The soft update journalling flag is located in the top 32-bits of
mnt_flag and was being lost due to this bug.

This fix was MFC'ed to 9 in -r230725 on Sun Jan 29 08:03:45 2012.
