Does UFS2 send BIO_FLUSH to GEOM when update metadata (with softupdates)?

  Your soulution could be merged with my one -- you've added special
 flag at BUF level, which could be good idea.

   But, on other hand, IMHO any non-ASYNC BUF should be converted
 to SYNC BIO. Now we break semantic of B_ASYNC flag -- don't guarantee
 sync operation on GEOM elvel when buffer request one (by not-setting
 B_ASYNC).
