svn commit: r231122 - head/sys/ufs/ufs

[Konstantin Belousov]

Author: kib
Date: Tue Feb  7 09:51:41 2012
New Revision: 231122
URL: http://svn.freebsd.org/changeset/base/231122

Log:
  Sprinkle missed calls to asynchronous UFS_UPDATE() in attempt to
  guarantee that all UFS inode metadata changes results in the dirtiness
  of the inodeblock.  Due to missed inodeblock updates, syncer was
  required to fsync each mount point' vnode to guarantee periodic
  metadata flush.
