  Log:
  SVN rev 182366 on 2008-08-28 09:19:50Z by kib
  
  In ffs_valloc(), ffs_vget() may fail because insmntque() refused to
  insert new vnode into the mount vnode list. Then, for the SU-enabled
  mount, ffs_vfree could create freefile dependency. This dependency can
  hang around forever since inode is not marked as IN_MODIFIED and
  correspondingly inodeblock may be not marked as dirty.
  
  After ffs_vget() fails, retry with FFSV_FORCEINSMQ, mark the inode as
  modified, and vput() it immediately. Take care of the dup alloc.
