svn commit: r231077 - head/sys/ufs/ffs

[Konstantin Belousov]

New Revision: 231077
URL: http://svn.freebsd.org/changeset/base/231077

Log:
  JNEWBLK dependency may legitimately appear on the buf dependency
  list. If softdep_sync_buf() discovers such dependency, it should do
  nothing, which is safe as it is only waiting on the parent buffer to
  be written, so it can be removed.
