Subject: [PATCH] - fixes to b_open - new UML patch 2.4.20-4 which works with
 Red Hat 9 - minor fixes to handling handles in open/close to avoid oopsing -
 fix erroneous mds_mfd_put in mds_open - fix the CVS tests added to sanity

- the tests exposed more problem in this branch, probably related to
  the lack of a file handle cache. Only good parts of the branch will
  be merged.
