From: Michal Privoznik <[email protected]> Our qemusecuritymock reimplements stat() (for the purpose of testing our DAC secdriver) and so far, for every path S_IFREG mode is set (i.e. pretending every path thrown into stat() is a regular file). Extend the mock so that a path can be directory (S_IFDIR).
