ufs: fix symlink creation on ufs2
Evgeniy Dushistov [Fri, 8 Feb 2008 12:20:16 +0000 (04:20 -0800)]
If we create symlink on UFS2 filesystem under Linux, it looks wrong under
other OSes, because of max symlink length field was not initialized
properly, and data blocks were not used to save short symlink names.
