  68  *              Permission checking modes for high level and low level
  69  *
  70  *      The choices for high and low lowel are independent, they have
  71  *      no effect on the library
  72  *
  73  *      Stick to the recommended values unless you understand the consequences
  74  *      on protection and performances. Use of cacheing is good for
  75  *      performances, but bad on security with internal fuse or external
  76  *      fuse older than 2.8
  77  *
  78  *      Possible values for high level :
  79  *              1 : no cache, kernel control (recommended)
  80  *              4 : no cache, file system control
  81  *              7 : no cache, kernel control for ACLs
  82  *
  83  *      Possible values for low level :
  84  *              2 : no cache, kernel control
  85  *              3 : use kernel/fuse cache, kernel control (external fuse >= 2.8)
  86  *              5 : no cache, file system control (recommended)
  87  *              8 : no cache, kernel control for ACLs
  88  *
  89  *      Use of options 7 and 8 requires a patch to fuse
  90  *      When Posix ACLs are selected in the configure options, a value
  91  *      of 6 is added in the mount report.
