Allowed kernel cacheing by lowntfs-3g when not using Posix ACLs

Browse Source 
Kernel cacheing of file attributes is usually not used by ntfs-3g,
because it has defects when dealing with hard linked files and directory
permission checks. Kernel cacheing is however possible when using
lowntfs-3g and not using Posix ACLs.
