* Permission checking modes for high level and low level
*
* The choices for high and low lowel are independent, they have
* no effect on the library
*
* Stick to the recommended values unless you understand the consequences
* on protection and performances. Use of cacheing is good for
* performances, but bad on security.
*
* Possible values for high level :
* 1 : no cache, kernel control (recommended)
* 4 : no cache, file system control
* 7 : no cache, kernel control for ACLs
*
* Possible values for low level :
* 2 : no cache, kernel control
* 3 : use kernel/fuse cache, kernel control
* 5 : no cache, file system control (recommended)
* 8 : no cache, kernel control for ACLs
*
* Use of options 7 and 8 requires a patch to fuse
* When Posix ACLs are selected in the configure options, a value
* of 6 is added in the mount report.
